Question

Assertion Like light radiation, thermal radiations are also electromagnetic radiation. Reason The thermal radiations require no medium for propagation. (A) if both Assertion and Reason are true and the Reason is the correct explanation of the Assertion (B) if both Assertion and Reason are true but the Reason is nor the correct explanation of the Assertion (C) if Assertion is true but Reason is false (D) if Assertion and Reason are false

Light radiations and thermal radiations both belong to electromagnetic spectrum. Light radiation belongs to visible while thermal radiation belongs to infrared region of

EM

spectrum.
Also

EM

radiations require no medium for propagation.

Q. Assertion Like light radiation, thermal radiations are also electromagnetic radiation.
Reason The thermal radiations require no medium for propagation.

Light radiations and thermal radiations both belong to electromagnetic spectrum. Light radiation belongs to visible while thermal radiation belongs to infrared region of $EM$ spectrum.
Also $EM$ radiations require no medium for propagation.
