g Suppose light travels from water to another medium, with an angle of incidence of 10o and an angle of reflection of 15o. (a) What is the index of refraction of the second medium

b.transmitters send radio waves, and receivers capture radio waves.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

i'm on my way to history not a mistory.
