Question

What is the momentum of a photon having frequency 1.5 x 10¹³ Hz?

विकल्प

• 3.3 x 10^-29 kg m/s

• 3.3 x 10^-34 kg m/s

• 6.6 x 10^-34 kg m/s

• 6.6 x 10^-30 kg m/s

Answer 1

3.3 x 10^-29 kg m/s

Explanation:

p = `"hv"/"c" = (6.63 xx 10 ^-34 xx 1.5 xx 10^13)/ (3 xx 10^8)`

= 3.3 x 10^-29 kg m/s
