Answer:
The pressure of a gas in a closed container increases if the volume of the gas decreases. Pressure and volume have inverse relationship which means if one increases the other decreases and vice versa. If pressure increases, volume of a gas decreases because there are a lot of empty spaces present between gas particles which are filled when gas particles come closer to each other due to applied of pressure.

Answer:
The amount of energy of a wave can be determined by measuring its wavelength, the distance between consecutive points of a wave.
Visible light is a type of radiant energy within the electromagnetic spectrum; other types of electromagnetic radiation include UV, infrared, gamma, and radio rays as well as X-rays.
The difference between wavelengths relates to the amount of energy carried by them; short, tight waves carry more energy than long, wide waves.
