Question

Solar water heater converts *

Light energy → Heat energy

Heat energy → Light energy

Electrical energy → Heat energy

Chemical energy → Light energy

​

Answer 1

Light energy → Heat energy

this your answer...!!

Answer 2

Light energy → Heat energy

Explanation :-

Solar heater absorbs light, and

thus photons of light are absorbed and the energy contained in them is converted to heat energy, which raises the temperature of water flowing slowly in contact with the plate and thus heat energy is transfered from plate to water.

Hence a solar heater converts light energy into heat energy.
