If she did, he could stand it better in the light.

If the input light distribution falls beyond the visible range, Af as expected, since Af.

If it pleases symphony audiences as a light, jolly piece, a series of impressions musically expressed, it succeeds.

If, in an unsharp image, a patch of light corresponds to an object point, the center of gravity of the patch may be regarded as the image point, this being the point where the plane receiving the image, e. g., a focusing screen, intersects the ray passing through the middle of the stop.

If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called " black ".

If the source emits light uniformly in all directions, the flux can be found by multiplying the intensity by 4π: a uniform 1 candela source emits 12. 6 lumens.

If it is removed, the light ceases.

If the glass is cooled quickly in the absence of a strong light source by putting ice on the glass or placing it in the freezer with the door almost closed, it turns backwards ( i. e. the silver sides trail ).

If light pressure were the cause of the rotation, then the better the vacuum in the bulb, the less air resistance to movement, and the faster the vanes should spin.

If the incident light is monochromatic, these sources all have the same phase.

If light consisted strictly of ordinary or classical particles, and these particles were fired in a straight line through a slit and allowed to strike a screen on the other side, we would expect to see a pattern corresponding to the size and shape of the slit.

If the width of the slits is small enough ( less than the wavelength of the laser light ), the slits diffract the light into cylindrical waves.

If the width of the slits is greater than the wavelength, the Fraunhofer diffraction equation gives the intensity of the diffracted light as:

If a ray tracing is then made as if a light wave ( as understood in classical physics ) is wide enough to take both paths, then that ray tracing will accurately predict the appearance of maxima and minima on the detector screen when many particles pass through the apparatus and gradually " paint " the expected interference pattern.

If the emulsion is dilute enough, higher-frequency and low-wavelength light will be scattered more, and the emulsion will appear bluer-this is called the " Tyndall effect ".

If applied to optical wavelengths, this manifests itself as a change in the colour of visible light as the wavelength of the light is increased toward the red part of the light spectrum.

If the incident light is unpolarised ( containing an equal mix of s-and p-polarisations ), the reflection coefficient is

If a laser is swept across a distant object, the spot of laser light can easily be made to move across the object at a speed greater than c. Similarly, a shadow projected onto a distant object can be made to move across the object faster than c. In neither case does the light travel from the source to the object faster than c, nor does any information travel faster than light.

If Lorentz symmetry can cease to be a fundamental symmetry at Planck scale or at some other fundamental scale, it is conceivable that particles with a critical speed different from the speed of light be the ultimate constituents of matter.

If the manner of his passing moves the nations to act in the spirit of his dedication the sore issues that plague the world can yet be resolved with reason and justice.

If the lever is pulled to clear a signal or move a switch, the tappet moves a short distance lengthwise at the same time.

If the vertex is at Af, and if the interior of C is on the left as one moves in the direction of increasing t, then every such corner can be found from the curve obtained by rotating C clockwise through 90-degrees about the vertex.

# If adiabats and isotherms are graphed severally at regular changes of entropy and temperature, respectively ( like altitude on a contour map ), then as the eye moves towards the axes ( towards the south-west ), it sees the density of isotherms stay constant, but it sees the density of adiabats grow.

If the creditworthiness of the issuer deteriorates ( e. g. rating downgrade ) and its credit spread widens, the bond price tends to move lower, but, in many cases, the call option part of the convertible bond moves higher ( since credit spread correlates with volatility ).

If the player to move has no legal moves, the game is over ; it is either a checkmate — if the king is under attack — or a stalemate — if the king is not.

If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to partially reverse the change.

If a neighboring atom moves to occupy the vacant site, the vacancy moves in the opposite direction to the site which used to be occupied by the moving atom.

If the defendant moves for a mistrial, there is no bar to retrial, unless the prosecutor acted in " bad faith ," i. e. goaded the defendant into moving for a mistrial because the government specifically wanted a mistrial.

If the prosecutor moves for a mistrial, there is no bar to retrial if the trial judge finds " manifest necessity " for granting the mistrial.

If that is the case, the thrower moves to the drop zone to play the next shot.

If five judges then the highest and lowest scores are discarded and the middle three are summed and multiplied by the degree of difficulty ( DD ), which is determined from a combination of the moves undertaken, in which position and from what height ).

If a particle of charge q moves with velocity v in the presence of an electric field E and a magnetic field B, then it will experience a force

If a charged particle moves in an electromagnetic field, its kinematic momentum is not conserved.

If anyone takes more or less than their bid, the deal moves to the left and the round is re-dealt.

* If only one end of Player A's tessera is open, Player B can use the above mentioned moves, or simply block the open end of Player A's tessera.

If a photon moves from one place and time – in shorthand, A – to another place and time – shorthand, B – the associated quantity is written in Feynman's shorthand as P ( A to B ).

If either the 2nd player chooses to move to the square diagonal to the first player or the first player's 2nd move is not to this square given the choice, then a starting position before flipping moves commence that differs from the standard Othello position arises.

If played poorly, this can poison later moves by causing players to flip too many pieces and open up many moves for the opponent.

If an object moves with angular velocity ω around a circle of radius r centered at the origin of the x-y plane, then its motion along each coordinate is simple harmonic motion with amplitude r and angular frequency ω.

If the air movement in the tunnel is sufficiently non-turbulent, a particle stream released into the airflow will not break up as the air moves along, but stay together as a sharp thin line.

If, on completion of a move, a player's token lands on the lower-numbered end of a " ladder ", the player moves his token up to the ladder's higher-numbered square.
