Question

Einstein’s work on photoelectric effect provided support for the equation(a) E = hv(b) E = mc²(c) E = $\frac{-Rhc}{n^{2}}$(d) K.E. = $\frac{1}{2}mv^{2}$

Answer 1

hey mate thecorrect option is a

Answer 2

According to the famous photoelectric effect invented by Einstein,we get the following mathematical formula of this effect;

K.E= ½ mv².

This mathematical formula was basically derived from the quantum theory of Planck.

With this mathematical formula we mainly calculate the amount of transferred energy into an electron, when a photon collides with that particular electron.

That's why the correct answer of this question is option d.
