Question

Light energy from the Sun reaches an ocean beach, where people are

walking. Which transfer of thermal energy involved in this scenario is an
example of radiation?
O A. From the sand to the ocean waves that strike the beach
O B. From the Sun to the sand
O C. From the sand on the beach to the bottoms of a person's feet
O D. From warm air over the beach to cooler air over the ocean

Answer 1

From the sun to the sand

• See sun's light energy is a thermal energy also as sun 's ray produces heat
• So when that comes contact with sand energy is transferred

Answer 2

Answer: B

Thermal energy can be transferred by three methods: conduction, convention, and radiation.

Radiation transfer occurs when there is no movement of matter for the exchange of energy.

hope this helps :)
