The given diagram exhibits the relationship between the wavelength of the electromagnetic waves and the energy of photons associated with them. The three points P, Q, and R marked on the diagram may correspond respectively to:
1
X-rays, microwaves, UV radiation
2
X-rays, UV radiation, microwaves
3
UV radiation, microwaves, X-rays
4
Microwaves, UV radiation, X-rays
Official Solution
Correct Option: (2)
To determine the correct correspondence of P, Q, and R with electromagnetic waves, we need to understand the relationship between wavelength, energy, and their position on the electromagnetic spectrum.
X-rays have short wavelengths and high energy photons.
UV (Ultraviolet) radiation has medium wavelengths and energy.
Microwaves have long wavelengths and low energy photons.
In the electromagnetic spectrum, energy and wavelength are inversely proportional: higher energy means shorter wavelength, and vice versa.Given this:
P: corresponds to X-rays since they are known for short wavelengths and high energy levels.
Q: corresponds to UV radiation which falls in the middle range for both wavelength and energy.
R: corresponds to microwaves characterized by long wavelengths and low photon energy.
Therefore, the correct order is: X-rays, UV radiation, microwaves
