Why can white light be split into Colours? White light is a mixture of many different colours, each with a different frequency . Light is refracted when it enters the prism, and each colour is refracted by a different amount. This means that the light leaving the prism is spread out into its different colours, […]

What happens if gas pressure is too high?
What happens if gas pressure is too high? High gas pressure can be just as bad for your furnace. That’s because it greatly increases the risk of furnace overheating. When this happens, all manner of internal components may become damaged by the excessive heat. What are four factors that determine the efficiency of a furnace? […]
What are two types of electric current?
What are two types of electric current? Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. Is gold good conductor? Gold is used as a contact metal in the electronics […]
Is electromagnetic force affected by intervening medium?
Is electromagnetic force affected by intervening medium? EM force does not need any intervening medium. Why is gravitational force independent of medium? Gravity is unipolar, attractive. So when it goes through a medium, there is no polarizing effect or polarizing forces. Thus the gravitational constant is independent of the intervening medium. Does electrostatic force depend […]
