How can light energy be used?

Answer 1

A light bulb: Electrical energy passes through a tungsten filament, heating it up to between 2527 ºC (2800 K) and 3027 ºC (3300 K), which causes the filament to glow brightly, converting the thermal energy to light energy.

Answer 2

Given enough molecular motion or vibration due to heat, the molecules will eventually give off photons -- ie, light energy. This can be either black body radiation or emissions from electron orbital changes.

Answer 3

light energy can be used :-

1)it is used as solar energy that is produced from the solar pannels when sunlight falls into them.these solar pannels when sunlight falls on them turn it to electricity!

hence,light energy is used!:)

Answer 4

Light has energy and that energy can be converted to heat and other forms of energy.

Everyone has had the simple experience of feeling the warmth of the sun on our skin.

The conversion of solar (light) energy to heat is is what warms the Earth each day.

Light is electromagnetic energy and all forms of electromagnetic energy can be converted to heat. Microwaves are electromagnetic energy and the heat food in microwave ovens every day.

Light can be converted to electricity as well and that is what happens in solar electric panels.

Answer 5

First of all, the term, 'thermal energy' is archaic and is no longer used. The modern term is 'internal energy'.

To answer your question, on a small scale, a thermocouple will convert internal energy into electrical energy.

On a large scale, a thermal power station's turbo-alternator converts the internal energy of steam into electrical energy,

Answer 6

Light energy can be used to generate electricity through solar panels, provide heat through solar thermal systems, or facilitate photosynthesis in plants to produce food. Additionally, light energy is utilized in technologies such as fiber optics for telecommunications and in various medical procedures like laser surgeries.

Answer 7

Light energy changes to heat energy by causing the molecules in a particular substance to vibrate due to the transfer of energy from the light waves to the molecules, which creates heat.
