Question

The diagram shows a man standing under a shelter on a sunny day. Given that the man feels hot, which of the following shows the processes of how thermal energy from the Sun reaches the man?

• A. Radiation - Conduction - Radiation
• B. Radiation - Conduction - Convection
• C. Radiation - Convection - Radiation
• D. Radiation - Convection - Convection

Answer 1

Answer: (A)

Radiation - Conduction - Radiation

$\text{As we know,}$

$\text{Radiation is energy that comes from a source}$

$\text{and travels through space and may be able to}$

$\text{penetrate various materials.}$

$\text{Conduction is the movement of heat through}$

$\text{a medium or passage.}$

$\therefore \text{Radiation - Conduction - Radiation shows how}$

$\text{thermal energy from the Sun reaches the man.}$

$\therefore \text{option (A) is correct.}$
