What does Transmittance really mean?

Transmittance is a word that we can use to describe how light or other forms of energy pass through a substance or material. You see, when light travels through something like a piece of glass or water, some of the light waves get absorbed by the material, while others are able to pass through. The amount of light that is able to pass through the material is called transmittance.

Let's imagine you have a glass window in your room. When the sun is shining outside, the light rays will hit the window and some of them will be able to go through, reaching your room and making it bright. That's because the glass has high transmittance. But have you ever noticed that some windows or sunglasses can be really dark, and not much light passes through them? That's because these materials have low transmittance, which means they absorb a lot of the light and only a small amount is able to come through.

Transmittance is like a window that lets us see what's on the other side. If the window is really clear and transparent, we can see everything clearly. But if the window is foggy or dirty, it becomes harder to see through. In the same way, transmittance tells us how well light or energy can pass through a material, allowing us to perceive what is on the other side.

Transmittance can also be used to describe how other forms of energy travel through different substances. For example, think about the sound that travels from your teacher's voice to your ears. The air in the classroom allows the sound waves to pass through easily, resulting in high transmittance. But if you were to go underwater and try to hear your teacher talk, the water would make it much harder for the sound waves to pass through, leading to low transmittance.

So, to sum it all up, transmittance is all about how much light or energy can pass through a substance or material. It tells us whether the material is clear and lets us see through it, or if it absorbs most of the light or energy and doesn't let much pass. Just like a window, transmittance helps us understand how well we can perceive what's on the other side.

Transmittance In a sentece

Learn how to use Transmittance inside a sentece

  • When you turn on a flashlight, the light from inside passes through the glass lens and goes out into the room. The transmittance is high because a lot of light is able to pass through the lens and reach the room.
  • If you wear sunglasses on a sunny day, the lenses help to reduce the brightness of the sunlight that reaches your eyes. The transmittance of the sunglasses is low because only a small amount of sunlight can pass through them.
  • A radio station broadcasts music and news to listeners. The radio waves travel through the air from the broadcasting station to your radio receiver. The transmittance of the radio waves is necessary for you to hear the radio programs clearly.
  • When you receive a message on your mobile phone, the signal travels through the air from the sender's phone to your phone. The transmittance of the signal is crucial for you to receive and read the message on your screen.
  • A car windshield allows you to see the road ahead while protecting you from wind and objects. The transmittance of the windshield helps you have a clear view of the surroundings while driving.
