Question

what is energy of photon of wavelength 0.01Å?​

Answer 1

Answer:

de Broglie wavelength λ=

p

h

Thus momentum of the photon p=

λ

h

where wavelength of the photon λ=0.01×10

−10

m

p=

0.01×10

−10

6.6×10

−34

p=6.6×10

−22

kg m/s

Answer 2

de Broglie wavelength  λ=ph

Thus momentum of the photon  p=λh

where wavelength of the photon  λ=0.01×10−10m

p=0.01×10−106.6×10−34

p=6.6×10−22kg m/s

So, the answer is option (C).
