Question

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:

• A. X-rays, microwaves, UV radiation
• B. X-rays, UV radiation, microwaves
• C. UV radiation, microwaves, X-rays
• D. Microwaves, UV radiation, X-rays

Hint:

Remember that shorter wavelengths correspond to higher energy photons. X-rays have the shortest wavelength and highest energy, followed by UV radiation and microwaves.

Answer 1

The Correct Option is B

In the given graph, the energy of the photons is inversely proportional to the wavelength. The higher the energy, the shorter the wavelength. X-rays have the shortest wavelength, followed by UV radiation and microwaves with the longest wavelength. Thus, the correct answer is option (B).
