the momentum of photon of wavelength 5,000 A° will be???? ​

Answer 1

Solution:-

Given:-

wavelength($\lambda$)= 5000 Å = 5 × $10^{-7}$m

Find:-

Momentum(p) = ?

By using De-broglie equation

wavelength = $\dfrac{h}{p}$

$\lambda$ = $\dfrac{h}{p}$

$p$ = $\dfrac{6.63 × 10^{-34}Js^{-1}}{5 × 10^{-7}m}$

After solving this we get,

$p$ = $1.32 × 10^{-27}kgm/s$

Hence, the momentum of a photon of wavelength 5,000 Å will be 1.32 × 10^-27kgm/s.
