Example of Everyday applications with Radiation

1. A fire-fighting suit needs bright and shiny outer layer so that it is slow to absorb heat energy from the fire.
2. During the day, infared radiation from the sun passes through the glass roof of the greenhouse. This warms up the soil and plants in the greenhouse. As the contents in the greenhouse get warm, they start to emit infared radiation. The infared radiation emitted by the contents in the greenhouse is slightly different compared to the infared radiation emitted by the Sun and is unable to pass through the glass roof. Therefore. the infared radiation emitted by the contents in the greenhouse gets trapped. The amount of infared radiation in the greenhouse gets built up over time, thus, causes the temperature in the greenhouse to rise.
