NEET Physics Question - Thermal Physics - Heat Transfer

Assertion (A): Most of the heat transfer that is taking place on earth is by convection.

Reason (R): Mostly heat radiation from sun are obtained in infrared region.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Within the Earth's atmosphere and oceans, convection is indeed the primary mechanism for heat distribution, making Assertion (A) true. However, the Sun's peak radiation is in the visible light spectrum (around `\(500\text{ nm}\)`), not predominantly in the infrared region. Therefore, Reason (R) is false.
