Question

13. The mass of hydrogen atom is 1.66 x
10-24g and Planck's constant is 6.64x
10-27erg-sec. The de Broglie wave-
length of a hydrogen atom moving
with a velocity half that of light is
equal to
1) 2.66 x 10-5A° 2) 2.66 x 10-13A
3) 2.66.10-10A 4) 2.66 x 10-27A​

Answer 1

Answer:

h=p/lambda

h=m×v/wavelength
