  1. heat energy only

  2. light energy only

  3. both heat and light energy

  4. none of these

Show answer
Correct Option: A
Explanation:

In the box type solar cooker, the heat from the sunlight is used to cook the food.

Water cannot be heated using a solar water heater on a.

physics solar equipment production of electricity from solar energy solar power alternate sources of energy solar power plant solar energy and its applications renewable and non-renewable resources renewable and non-renewable sources of energy generation of electricity

  1. windy day

  2. sunny day

  3. cloudy day

  4. hot day

Show answer
Correct Option: C
Explanation:

Solar water heater works on solar radiation falling on it. It requires solar light for generating enough heat to heat water. During cloudy days, Sun is obstructed by clouds, and the light incident of the solar panels will be inefficient to make the heater work.
