In order to break a chemical bond in the molecules of human skin, causing sunburn , a photon energy of about `3.5 eV` is required. This corresponds to wavelength in the

infrared region

X-ray region

visible region

ultraviolet region

Text Solution

Verified by Experts

The correct Answer is:

`lambda = (h c)/(E) = (1240 eV - nm)/(3.5 eV) = 354 nm`
This wavelength is in the ultraviolet region.
