A photon of radiation of wavelength 4000...

A photon of radiation of wavelength 4000 Å has an energy E. The wavelength of photon of radiation having energy 0.5 E will be

A

2000 Å

B

8000 Å

C

4000 Å

D

6000 Å

Text Solution

Verified by Experts

`E=hv=hc/(lamda),(E_(1))/(E_(2))=(lamda_(2))/(lamda_(1)),E/(0.5E)=(lamda_(2))/4000` or `lamda_(2)=8000Å`
