5 Applications of refraction of light in daily life
As we already discuss about examples of refraction of light. post link given below. Now, we try to understand 5 most common application of refraction we use in our day to day life. So, before any wasting of time. Given below are the 5 applications of refraction of light in daily life.
5 Applications of refraction of light in daily life
- Refraction of light can be seen in measuring scale.
- Microscope works on the application of refraction of light.
- Refraction is used in working telescope.
- Our eye works on the application of refraction of light.
- Eye contact lens works on the application of refraction.
Now, we try to understand all the above applications of refraction of light in detail one by one.
(1.) Refraction of light in measuring scale
In our student life we have used measuring scale. And at that time everyone must observe one thing. When we tried to see through the measuring scale, we noticed the formation of some colorful pattern in scale. So what was that pattern? And Why formed? The answer is that pattern was due to the light entering in the measuring scale. And they formed due to the refraction of light. Know how?
When light falls on our eyes passing through the measuring scale. It get refract or bend at the edge of the measuring scale. Because light is coming from air (medium 1) and then get enters into measuring scale (medium 2). And we studied that when light enters from one medium to another medium, it gets bends. So due to the change in medium, the speed of light get decreases, And colorful pattern formed.
(2.) Microscope works on the refraction
We all see the microscope in our school laboratory. If we noticed that there is some small lenses fitted in microscope. So what is that lens? And what is their work? So before answering all these questions, we have to know about microscope.
A microscope is an instrument through which we can see micro-organism, bacteria, viruses etc. which is not possible to see from our naked eyes.
The lenses used in microscope to see micro-organism is convex lens. That lens magnifies the object so that it appears bigger than original size.
When we try to see through microscope, the light coming from outside get enters in our eyes through these lenses. Hence, we can say that the refraction of light takes place in microscope.
(3.) Refraction in working telescope
In telescope there is also presence of lenses. We use telescope to see starts and the behaviour of the planets. Scientist also use telescope to notice the position of stars and planets. Please note that telescope is just quite similar to microscope.
Telescope also works on the application of refraction of light. This happens as follows: When we see stars and planet through telescope. The lenses present in it get refract the light coming from stars and planet and bend it through some angles. So that the stars and planets looks closer to our eyes.
(4.) Eye works on the application of refraction of light
Apart from microscope and telescope. Human eyes are also works on the application of refraction of light. This is because of the presence of convex lenses in our eyes. Convex lenses refract or bend the light wave coming from outside and divert it in our retina. So retina forms images which is inverted. But our mind rearrange that image.
Our eye are the best application of refraction of light.
(5.) Eye contact lens works on the application of refraction
Those people who have not clear vision. They uses eye contact lenses for clear view. So what is that lens made up of? That lenses are convex lens.
Those person who has weak sightedness. They wears eye contact lens because as we know that convex lenses are used in eye contact glass. So it helps to refract the light.
