Solution
The given diagram exhibits the relationship between the wavelength of the electromagnetic waves and the energy of photon associated with them. The three points P, Q and R marked on the diagram may correspond respectively to X-rays, UV radiation, microwaves.
Explanation:
E = `(hc)/lambda`
Energy and wavelength are inversely proportional. wavelength of microwave > wavelength of UV > wavelength of X-rays.
Hence,
P = X-rays
Q = UV radiation
R = Microwave
