 Hello and welcome back to another episode of Physics Partner. In today's video we are going to discuss the concept of heat transferred through radiation with real life examples. As many of you already know radiation is a process where energy is transferred from one body to another through electromagnetic waves. This process of radiation can occur across a vacuum which makes it unique from other forms of heat transfer like conduction of heat or convection of heat. When we refer to a body radiating heat we are talking about its transfer of energy to the surrounding environment in the form of electromagnetic waves. These waves are responsible for transferring energy from hotter to cooler bodies. So the question arises why is this important in the real life? Let's now look at some real life examples to understand this concept better. Have you ever wondered why a car parked under the scratching sun becomes unbearably hot inside? That's because of the sun's rays fall on the car's surface. They transfer heat to the car body, heating it up. This heat is then radiated from the car's body into the surrounding air. This same effect makes wearing black clothes in the summer heat a lot less comfortable than wearing white clothes. Another example of radiation in everyday life is the heat emitted by the stove when cooking food. As the stove burner heats up it emits radiation that is absorbed by the pot and the food inside it. This radiation causes the molecule in the food to vibrate faster leading to an increase in temperature. One of the most amazing examples of radiation is the sun. The sun radiates heat and light which are essential for life on earth. The rays of the sun reach our planet, transfer heat to the earth's surface and keep our planet warm. It is also responsible for photosynthesis in the plant that release oxygen, making it crucial for our existence. It is not just the sun that demonstrates the effect of radiation. Other celestial bodies such as the moon also exhibits this phenomenon. During a full moon the radiation that is reflected back toward causes the moon's surface to appear brighter than other times. Now let's take it up a notch and discuss how radiation is used in industries. Heat transferred by radiation is a significant process in various industries including space exploration. Space craft and space suit needs to be well protected against solar radiation and extreme temperature during space travel. Hence radiation is used in space technology to heat transfer to the surrounding environment and maintain the temperature inside the spacecraft. In the food industry a radiation process is used to sterilize food which kills germs and prolongs the food's shelf life. Similarly radiation is used in medical science to diagnose and treat patients with cancer. In summary heat transfer by radiation is a crucial phenomenon in the real world and plays a significant role in our daily lives. Understanding this process of transfer of heat is essential to protect ourselves and our environment.
