Question

State whether the following statement is true or false:The cause of the refraction of light is that  light travels at different speeds in different media.

Accepted Answer

:The given statement is true.Concept: Refraction is the term for the bending of light (as well as sound, water, and other waves) as it passes from one transparent substance into another. This bending via refraction makes lenses, magnifying glasses, prisms, and rainbows all conceivable. Even our eyes depend on the bending of light. Without refraction, our retina would not be able to focus light.As everyone is aware, light refracts as it travels at an angle through a substance with a specific refractive index (optical density). This shift in direction is brought on by a change in speed. For instance, light slows down and continues to move in a different direction or at an angle when it passes through water from air.Two things influence how much bending occurs:A substance that permits light to refract (bend) more can alter its speed, causing it to accelerate or decelerate more.Angle of the incident ray: If light reaches the material at a larger angle, there will be a greater degree of refraction. On the other hand, light will slow down but not change direction if it enters the new material from the front (at 90 degrees to the surface). A 90-degree imaginary line is created on the surface of the two materials, and it is used to determine all angles.Light slows down as it travels through a substance (like glass) that has a greater refractive index than air. In the direction of the straight line, the light sways.Light accelerates as it passes through a substance with a lower refractive index, such as glass and air. The light veers off the straight path.Light can slow down and shift direction more when it enters a substance with a higher refractive index.The response given above indicates that the primary reason for refraction is a change in the speed of light brought on by a change in the material's density.Light moves through different types of medium at varying rates, thus that is the right response.Hence, the given statement is true.

State whether the following statement is true or false:

The cause of the refraction of light is that light travels at different speeds in different media.
