Question

Which of the following is called heat radiation?
(a) X-rays
(b) γ-rays
(c) Infrared radiation
(d) Microwave

Answer 1

Answer:

(c) Infrared Radiation

Answer 2

Heat radiation refers to the emission of thermal energy in the form of electromagnetic waves. Out of the options given, Infrared radiation (c) is referred to as heat radiation. Infrared radiation has a longer wavelength and lower frequency than visible light, and it is responsible for warming our skin and objects around us.

X-rays (a) are high-frequency electromagnetic waves that are used in medical imaging. They have a shorter wavelength and higher frequency than visible light and can penetrate solid objects, making them useful for medical purposes.

Gamma rays (b) are high-energy electromagnetic waves that are produced by radioactive decay or high-energy events like supernovae. They have a higher frequency and shorter wavelength than X-rays.

Microwaves (d) are electromagnetic waves that are in the lower frequency range of the electromagnetic spectrum. They are used for a variety of applications, including communication, cooking, and remote sensing.

In summary, Infrared radiation is called heat radiation and X-rays, gamma-rays, and microwaves are different forms of electromagnetic waves with different applications.
