Potential energy is the energy by virtue of object's height & kinetic energy by virtue of it's motion!
Hope this helps!

Given
Speed of Primary wave
Speed of secondary wave
difference in timing of two waves are
Suppose both travel a distance of d km then
Subtract (ii) from (i)
Answer:
"jumps" from one energy level down to another lower energy level.
Explanation:
The light observed in such a spectrum is emitted when an electron in an atom "jumps" from one energy level down to another lower energy level. When an electron does this , it emits energy equal to difference in the energy level of two shell in which the electron jumps.
And this emitted light is separated out into individual colors using a prism or diffraction grating and a few lines of colored light are seen.
