Du ITEM BANK: Move to Bottom
Best with a smooth surface
If not for this behavior of light, your mirror
would not work!
Light wave changes speed
Most microscopes and some telescopes
use lenses that take advantage of this
behavior of light
This occurs when light bounces off of a
surface
This behavior of light allows the lenses in
your glasses to bend incoming light waves
This occurs when light moves from
medium to another, Like water to air
Reflection
Refraction

Atruck going 15 kmôź°€h has a head-on collision with a small car going 30 kmôź°€h. which statement best describes the situation? (a) the truck has the greater change of momentum because it has the greater mass. (b) the car has the greater change of momentum because it has the greater speed. (c) neither the car nor the truck changes its momentum in the collision because momentum is conserved. (d) they both have the same change in magnitude of momentum because momentum is conserved. (e) none of the above is necessarily true. 2. a small boat coasts at constant speed under a bridge. a heavy sack of sand is dropped from the bridge onto the boat. the speed of the boat (a) increases. (b) decreases. (c) does not change. (d) without knowing the mass of the boat and the sand, we can’t tell.

Aball with a mass of 1.5 kilograms is tied to the end of a rope. the ball is pulled to a height of 0.5 meters above the ground and released. the ball has joules of potential energy at position b. at position a, all of the energy changes to kinetic energy. the velocity of the ball at position a is meters/second. assume there’s no air resistance.
