Concept:

The ozone layer in the Earth's stratosphere plays a crucial role in absorbing harmful ultraviolet (UV) radiation from the sun. This absorption process protects living organisms on Earth from potential damage. The ozone layer also absorbs certain types of electromagnetic radiation such as X-rays.

Calculation:

We know that the ozone layer absorbs ultraviolet (UV) rays, which are harmful to living organisms. Additionally, it also absorbs X-rays to a certain extent.

⇒ Ozone layer absorbs X-rays and ultraviolet rays.

∴ The correct answer is option 4.

Q6.The angular width θ of a distant star can be measured by the Michelson radiofrequency stellar interferometer (as shown in the figure below). The distance h between the reflectors M1 and M2 (assumed to be much larger than the aperture of the lens), is increased till the interference fringes (at P0, P on the plane as shown) vanish for the first time.
