Find the wavelength of electromagnetic waves of frequency `5xx 10^(19)` Hz in free space. Give its two applications.

Text Solution

Verified by Experts

`lambda = c/v = (3xx 18^(18))/(5xx10^(19))= 6xx10^(-12) m = 0.06 Å`
This wavelength corresponds to X - rays which are used :
(i) as a diagnostic tool.
(ii) as a treatment for certain forms of cancer.
