A light wave of frequency 5xx10^14 Hz en...

A light wave of frequency `5xx10^14 Hz` enters a medium of refractive index `1.5`. In the velocity of the light wave is ….. And its wavelength is ……

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`v_(2)=(3xx10^(8))/(1.5)=10^(8)m/s,`
`lamda_(2)=(v_(2))/(v)=(2xx10^(8))/(5xx10^(14))=0.4xx10^(-6)m`
