Bob is threatening tom’s life with a giant laser with wavelength (650 nm), a distance (d = 10 m) from the wall james is shackled to. (he is still free to move along the wall.) bob has set up a double slit experiment and tom must figure out where to position himself such that he is at a point of destructive interference to survive. if the double slit separation is d = 5 μm, where can tom stand to avoid a laser-full demise?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
