Answer:

1. Radiant energy is a form of electromagnetic energy. It can take the form of visible waves – which is what we call light energy – or invisible waves such as radio waves or x-rays. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy.
2. Heat and light are different but they are both forms of energy. Heat is a form of kinetic energy contained in the random motion of the particles of a material. Light is a form of electromagnetic energy. As with other forms of energy, heat energy can be transformed into light energy and vice versa.
3. Radiant energy is the energy of electromagnetic waves. These waves can travel through space. Electromagnetic radiation is made up of tiny particles called photons – think of them as little packets of energy.
4. Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. Mechanical energy can be either kinetic energy (energy of motion) or potential energy (stored energy of position).
