Why is light refracted when it passes from air to water? a) light slows down when it enters water b) forces from the water molecules bend the light c) the motion of the water bends the light d) the water is often cooler

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
