# Level of refraction depends on what?

• yipkawa
In summary, the spectrum is a range of colors that appear when a light beam passes through it. Each color has a unique wavelength, frequency, and speed. As light travels through different materials, its speed and wavelength may change, while the frequency remains the same. This can cause different colors of light to refract at different angles. The wave model of light is a simplified explanation, while the more accurate explanation is found in quantum electrodynamics.

i am perplexed at the spectrum.
when a light beam passes through the spectrum,different color of light appears. is the wavelength, frequency, and speed different in different color of light? is the wavelength of the light changes in the spectrum?
:!) the level of refraction depends on what? wavelength, frequency, or speed ?
thanks

White light is made of a combination of different frequencies of light. The frequency is the distinctive characteristic of each color.

As a wave of a certain frequency travels at a certain speed, it will have a wavelength that is (speed/frequency). When a wave changes speed (by going into a new medium) the frequency stays the same, but it will have a different wavelength.

Different frequencies travel through transparent materials at slightly different speeds. This is due to smaller wavelengths (higher frequencies) interact more often with smaller particles within the material.

Since the angle of refraction depends on the ratio of speeds inside and outside the material, different colors of light will refract at slightly different angles.

This is using the "wave model of light" as an explanation which is rather unsatisfactory when studying higher levels of Physics. The "more correct" explanation is known as "quantum electrodynamics" or QED. You can study this as you get your Master's degree.

The level of refraction depends on the properties of the medium the light is passing through, such as its density and composition. This can affect the speed of light and therefore the frequency and wavelength of the light. In the spectrum, the different colors of light have different wavelengths and frequencies, which can cause them to refract at different angles. This is due to the phenomenon of dispersion, where the different wavelengths of light are separated as they pass through a medium. So, to answer your question, the wavelength, frequency, and speed can all be affected by the level of refraction in a medium. I hope this helps to clarify your confusion about the spectrum.

## What is refraction?

Refraction is the phenomenon of light bending as it passes through different mediums, such as air, water, or glass.

## What factors affect the level of refraction?

The level of refraction is affected by the speed of light in different mediums, the angle at which the light enters the medium, and the density of the medium.

## How does the speed of light affect refraction?

Light travels at different speeds in different mediums, and this affects the degree to which it bends when passing through them. For example, light travels slower in water than in air, causing a greater level of refraction.

## Why does light bend when passing through a medium?

Light bends because it changes speed when it enters a new medium, causing a change in direction. This is due to the change in density and the interaction between the light and the atoms in the medium.

## How does the angle of incidence affect refraction?

The angle at which light enters a medium also affects the level of refraction. If the light enters at a perpendicular angle, it will not bend, but as the angle becomes more oblique, the degree of refraction increases.
