The relation between frequency, F, and wave length, L of the light is:

F = c / L, where c is the speed of light

Then, L = c / F = 3.00 x 10^8 m/s / 7.26 x 10^14 s^-1 = 0.413 x 10^ -6 m = 4.13 x 10 ^-7 m

This diagram shows that Al can see the reflections of Ed and Fred in the mirror. Which two students can both see the reflections

vazorg [7]

Answer:

Cy and Di

Explanation:

We cannot tell exactly where the right end of the mirror is, but if we assume it is short of allowing Ed and Fred to see each other, we have the following:

Cy can see Cy and everyone to the right

Fred can see Di and everyone to the left

The only two that can see all of Cy, Di, Ed, and Fred are Cy and Di.

_____

If the mirror extends far enough to the right for Ed to see Fred, then all of Cy, Di, and Ed can see the four folks of interest.

A sky-diver jumps from a stationary balloon. His initial downwards acceleration is 10m/s².

Tatiana [17]

Explanation:

a. The force acting down is gravity, on Earth gravity is 10 m/s^2. When the skydiver jump, the acceleration will start out as -10 m/s^2, but it will eventually equals the air resistance , which is called terminal velocity.
