Matter waves (DC Broglie waves)

Question

What should be the velocity of an electron so that its momentum becomes equal to that of a photon of wavelength 5200 $A^{0}$ ?

Moderate

A

700 m/sec
B

1000 m/sec
C

1400 m/sec
D

2800 m/sec

Solution

According to de Broglie’s equation momentum $v = \frac{h}{m λ} = \frac{6.62 \times 10^{- 34}}{9.1 \times 10^{- 31} \times 5.2 \times 10^{- 7}} = 1400 m / s$
