Radiant energy is a type of energy that comes from light and heat. When we turn on a light bulb or feel the warmth of the sun on our skin, we're experiencing radiant energy.
Think of it like a game of catch. Your friend throws a ball (like the sun or a light) towards you, and you catch it (your skin or a wall). When you catch the ball, it transfers its energy to you. This is like how radiant energy transfers its energy to objects, like the sun transferring energy to Earth or a light bulb transferring energy to a room.
Radiant energy is also used in science, like when we use heat radiation to cook food in a microwave or use light radiation to take pictures with a camera. Basically, radiant energy is light and heat energy that we experience and use every day.
