The product of frequencyof light and wavelength is equal to .....

A

Redberg’s constant

B

Plank.s constant

C

Energy of photon

D

Velocity of light

Text Solution

Verified by Experts

The correct Answer is:
D
`lambda=(h)/(mv)`
`=(6.26xx10^(-34)xx10^(2))/(9.1xx10^(-31)xx10^(8))`
=`7.27xx10^(-10)` m
