Explanation:

The wavelength is defined as

Where represents the wavelength, the speed of the wave which is a constant and is the frequency of the wave,

In this case, we know

, where

Replacing these given values in the formula, we have

But, we know that

So, we use the equivalence to transform the wavelength from meters to nanometers.

Therefore, the wavelength is 413.2 nanometers, approximately.

that would be because of both gravity and friction. so     c

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.
