NEL 10.1 Light Energy and Its Sources 291 Thermal energy can heat a metal to such a high temperature that it emits light. This light ranges from dull red to yellow to white and blue-white as the metal gets hotter. The colour of the emitted light indicates when the molten metal is ready to be poured. Light from Phosphorescence
The Sun is the major source of light for the earth. The sun is a massive ball of fire, at the centre of which nuclear fusion produces massive energy. This energy comes out as heat and light.
Some light bulbs get hot and are a heat source. You can use the temperature sensor to measure the amount of heat given off by a light bulb. Some light bulbs are energy efficient. Energy efficient bulbs emit light, but lose very little heat, so they are not a heat source.
identify conventional and non-conventional sources of energy used in India; distinguish between renewable and non-renewable sources of energy; describe various types of sources of energy e.g. fossil fuels, water, wind, biomass, sea, geothermal, nuclear energy; recognise that the sun is the ultimate source of energy;
