Question

which of the following radiations has the highest frequency ? microwaves visible light x-rays infrared

Explanation:

In the electromagnetic spectrum, the order of increasing frequency is: microwaves < infrared < visible light < X - rays. X - rays have a much shorter wavelength compared to the other options (microwaves, visible light, infrared). According to the relationship \(c = \lambda f\) (where \(c\) is the speed of light, \(\lambda\) is wavelength, and \(f\) is frequency), when \(c\) is constant (\(c = 3\times10^{8}\space m/s\)), a shorter wavelength (\(\lambda\)) corresponds to a higher frequency (\(f\)).

Answer:

X - Rays
