Do all colors refract at the same angle when entering a medium?

No, the fact of the rainbow demonstrates that the different wavelengths refract at different angles. If they didn't then the rainbow would be all one colour.

How does critical angle depend on color of light?
The critical angle of refraction depends on the wavelength of light, which is associated with color. Different colors of light have different wavelengths, causing them to refract at different angles. This is why we see rainbows when white light is dispersed into its various colors.
What angle of waves do not bend when entering a new medium?
sharp angle
Why does the light change angle when entering the prism?
When light enters a prism, it slows down and bends because it changes speed as it moves from one medium (air) to another medium (glass) with a different refractive index. This change in speed causes the light to bend, or refract, as it enters the prism.
What refract means?
It means that light changes its direction when it passes from one medium to another - for example, from air to water.
Why can white light refract to show all the colours of the rainbow?
White light is composed of a spectrum of colors with different wavelengths. When white light enters a medium like glass or water, each color refracts at a slightly different angle due to their different wavelengths. This separation of colors produces the spectrum of colors we see in a rainbow.
When light rays enter a medium at an angle they?
undergo refraction, where the speed and direction of the light rays change due to the change in the medium's optical density. This bending of light rays is due to a change in the velocity of light as it travels from one medium to another.
What refract means?

What angle of waves do not bend when entering a new medium?
sharp angle
How do light refract?
when light travels from rarer medium(which has relatively lower density) to a denser medium(which is of relatively higher density) the angle of incident light and refracted light is less than 180 degree(when the angle is considered at the point of incidence) and when the light travels from a denser to a rarer medium the angle will be greater than 180 degree.
How is light refracted when the angle of incidence was 0?
One possibility is that the medium the light is supposed to refract from is a metamaterial, an artificially created material with a negative refractive index.
How does critical angle depend on color of light?
The critical angle of refraction depends on the wavelength of light, which is associated with color. Different colors of light have different wavelengths, causing them to refract at different angles. This is why we see rainbows when white light is dispersed into its various colors.
What behavior describes two sides of a wave moving at different speeds upon entering a medium at an angle?
Refraction.
What do we use to refract light?
A transparent/translucent medium with a density that is different to the one it has just left is necessary to diffract light. For example, you could shine light into a block of glass to diffract it at a different angle to when it entered.
What will a wave entering a new medium at an angle undergo?
A wave entering a new medium at an angle may undergo reflection, refraction, or both. The specific behavior depends on the different properties of the two media it is transitioning between, such as their densities and refractive indices.
Does the principle of optical reversibility hold for reflection as well as refraction?
Yes, the principle of optical reversibility holds for both reflection and refraction. This means that the path of light is reversible, so if a light ray can travel from point A to point B, it can also travel back from point B to point A.
When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
Why does a prism break down white light into all the rainbow colors?
A prism can break down white light into its component colors because of a phenomenon called dispersion. When white light enters the prism, each color of light travels at a different speed and is refracted (bent) by a different angle. This separation of colors causes them to spread out and form a spectrum of colors, creating the visible rainbow.
