When light enters a prism, it will refract, or bend, as it passes through the prism due to the change in speed caused by entering the different medium. This bending effect causes the white light to split into its different colors, creating a spectrum as a result of dispersion.

How does light enter a prism?
Light enters a prism by passing through one of its flat, polished surfaces. This surface acts as the entry point for the light, causing it to refract or bend as it enters the prism.
If a light ray is traveling from air into a glass prism how will the direction of the light ray change after it enters the prism?
The light ray will bend towards the normal (perpendicular line to the surface of the prism) as it enters the glass prism. This is due to the change in speed of light as it transitions from air to glass, causing refraction.
How many times is white light refracted when passed through a prism?
Two times. One when the light beam crosses the air-prism interface and enters the prism and a second time when the beam crosses the prism-air interface on its way out of the prism.
What is the term for the change in direction of the light as it enters the prism?
The term for the change in direction of light as it enters a prism is called refraction. This is caused by the light wave bending as it travels through the prism due to the change in speed caused by entering a different medium.
What happens after the light enters the prism?
When light enters a prism, it refracts into different colors due to the varying speeds of light in different mediums. This separation of colors is known as dispersion and creates a rainbow spectrum.

What a prism does to light?
As the light passes through the prism, the resulting effect is called a 'refraction'. In other words, the light enters from one side of the prism and is then 'redirected' at a right angle as it exits the prism.

Why does light exit the prism differently than it enters it?

What will happen when a ray of light is shone at a glass prism?
When a ray of light is shone at a glass prism, it will refract as it enters the prism, then undergo total internal reflection if the angle of incidence is greater than the critical angle, and finally refract again as it exits the prism. This results in the dispersion of light into its component colors due to differences in the refractive indices for different wavelengths.
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.
Is light reflected twice in a prism?
Yes, light is reflected twice in a prism - once when it enters the prism and once when it exits. The double reflection is what causes the splitting of light into its various colors, known as dispersion.
Which diagram correctly shows the path of light through a glass prism?
Diagram B correctly shows the path of light through a glass prism. Light enters the prism, bends towards the base of the prism, then exits the prism and continues in a straight line.
What is it called when light enters a prism?
When light enters a prism, it undergoes refraction, or bending, due to the change in its speed as it passes from one medium to another. This causes the light to separate into its different colors, creating a rainbow effect known as dispersion.
