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.
In the electromagnetic spectrum, energy and wavelength are inversely proportional: higher energy means shorter wavelength, and vice versa.Given this:
Therefore, the correct order is: X-rays, UV radiation, microwaves
If vector \( \mathbf{a} = 3 \hat{i} + 2 \hat{j} - \hat{k} \) \text{ and } \( \mathbf{b} = \hat{i} - \hat{j} + \hat{k} \), then which of the following is correct?
