What is denser and rarer medium

Thus, a medium in which light travels faster is called an optically rarer medium and, the medium in which light travels slower is called an optically denser medium. Byju's Answer.

Every time we pick up a glass of water, we witness a fascinating phenomenon that highlights the difference between denser and rarer mediums. What is a denser and rarer medium? Have you ever noticed how a straw placed in a glass of water appears bent at the surface? This intriguing optical illusion occurs due to the varying refractive indexes of water and air. It is just one example that showcases the impact of medium density on the behavior of light. In this article, we will explore the concept of denser and rarer mediums, their characteristics, and how they play a vital role in understanding the interaction of waves and light with different substances.

What is denser and rarer medium

Some rarer media include wood, plastic, glass, and metal. Denser mediums are usually harder to cut, shape, or manipulate because they are denser than air. However, denser materials such as metal and plastic can be split or cut easier than rarer materials like wood or skin. Denser material does affect sound because it is not very good at transmitting noise, especially if it transmits a lot of vibration within the material. For example, if someone were to walk across a floor made of plastic on which someone was playing a pipe organ, their footsteps would barely be heard amongst the thumping sounds of the organ playing in the background. Denser material can block sound from traveling. In a library for example, it is important to keep out other noises. If people are trying to keep the noise of other things outside the library, they may wish to use denser materials such as glass, metal, or plastic which will completely block the noises coming in from outside the library and make it far easier for people to study or read quietly in the library than if they used an unscreened door and thin walls. The person who chooses which medium is clean enough is the person who is using and cleaning the object. For example, if a nurse has to clean a certain tool, she will use soap and water to clean it because that medium is absorbed by skin. If someone else uses the same tool, they would most likely use alcohol or another type of cleaner because their skin can also absorb that fluid as easily as water.

The refractive index measures how much a medium bends or refracts light as it passes through. Air, gases, and even a vacuum can be considered examples of rarer mediums.

This is true as long as the light rays are travelling in the same medium having the same optical density throughout. If, however, the light rays are made to go from one transparent medium, to another transparent medium, they change their direction or bend at the boundary separating two media. For example, when light rays travelling in air go into another medium say glass, they change their direction or bend on entering the glass medium. The bending of the ray of light when it travels from one medium to another is called refraction of light. Air, glass, water, alcohol, etc. Different media are said to have different optical densities. The speed of light depends on the optical density of the medium. Therefore, light travels with different speeds in different media having different optical densities.

Air, gases, and even a vacuum can be considered examples of rarer mediums. Some denser media include rubber and human skin. Rarer mediums have a lower density, which means they have less mass per unit volume. Denser material can block sound from traveling. Glass falls in the same category for some reason. Denser mediums, with their closely packed particles, cause light to bend more significantly when transitioning from a rarer medium. However the speed of light in other media is less than this. This is why glass lenses are commonly used in optics to manipulate light and focus it. By utilizing the varying refractive indexes of denser and rarer mediums, lenses can bend and focus light rays to create images, correct vision problems, and enhance optical systems. However, denser materials such as metal and plastic can be split or cut easier than rarer materials like wood or skin. It is just one example that showcases the impact of medium density on the behavior of light. One of the essential characteristics of denser mediums is their higher refractive index. The most obvious difference between them is the density.

Air, gases, and even a vacuum can be considered examples of rarer mediums. People can sneak around undetected in dense materials because their sound does not travel far before being muffled by their surroundings. This makes denser mediums useful for stealth. For example, if someone were to walk across a floor made of plastic on which someone was playing a pipe organ, their footsteps would barely be heard amongst the thumping sounds of the organ playing in the background.

When the light goes from denser to a rarer medium, the deviation of light in its path is less. Dense mediums include plastic and metal.
