What is the ratio between the energies of two radiations one with a wavelength of 6000Ã… and other with 2000Ã…?

Text Solution

Verified by Experts

`lamda_(1)=6000`Ã… and `lamda_(2)=2000`Ã…
`E_(1)=h.(c)/(lamda_(1)) and E_(2)=h.(c)/(lamda_(2))`
Ratio, `(E_(1))/(E_(2))=(h*c)/(lamda_(1))xx(lamda_(2))/(h*c)=(lamda_(2))/(lamda_(1))=(2000)/(6000)=(1)/(3)`
or `E_(2)=3E_(1)`.
