It DOES reflect. Straight back to where it came from.

How can you deviate light on 180 degree from right angled prism?
Enter the light perpendicular to the hypotenuse of the Prism above or below the center of the hypotenuse. The light will reflect off the two non-hypotenuse sides and reflect back out in the opposite direction, 180 de Save grees.
Does a mirror reflect without light?
light is needed to reflect an image off a mirror...no light no reflection
Which smooth surfaces reflect light?
Any smooth surface will reflect light. The better question is "How much light does each kind of smooth surface reflect?"
Is speed of light in vacuum and medium same?
No, light in a medium will travel at a slower speed.
At what angle does a light ray reflect off a mirror?
It reflects at like 45 degrees I think. No, it reflects off at the same angle it hits the mirror. If the light wave hits the mirror at a 30o angle on the left side, it will reflect off at a 30o angle on the right side. Scientists usually measure these angles from an imaginary line perpendicular to the mirror at the point where the light wave hits the reflecting surface; sounds awkward, but it makes the math easier.
Will a light wave refract if it enters a new medium perpendicular to the surface Explain?
No, a light wave will not refract if it enters a new medium perpendicular to the surface. This is because refraction occurs when light enters a new medium at an angle, causing it to change speed and direction. When light enters perpendicular to the surface, there is no change in speed or direction, so refraction does not occur.
Would you be able to observe the refraction of light if the incident light were perpendicular to the medium?
No, you wouldn't be able to.
Why light passes undeviated falling straight on a refracting medium?
When light enters a refracting medium, its speed changes due to the change in optical density, which causes the light waves to bend. If the light is entering the medium perpendicular to the surface, it will not bend, as there is no change in angle and no deviation occurs.
When light travels from a denser medium to a rarer medium it bends away from the normal Is it possible for the light ray to reflect back in the same medium?
Yes, when light travels from a denser medium to a rarer medium and strikes the interface at an angle greater than the critical angle, total internal reflection can occur. In this case, the light ray reflects back into the denser medium instead of refracting into the rarer medium.
Why type of waves has the medium moving perpendicular to the direction of the wave movement?
Transverse waves have the medium moving perpendicular to the direction of the wave movement. Examples include light waves and electromagnetic waves.
What is a wave called in which the medium vibrates perpendicular to the motion of the wave?
A wave where the medium vibrates perpendicular to the motion of the wave is called a transverse wave. Examples include light waves and electromagnetic waves.
What waves occur when the motion of the medium is at right angles (perpendicular) to the direction of the wave.?
Transverse waves occur when the motion of the medium is perpendicular to the direction of the wave. In these waves, the particles of the medium vibrate in a direction that is perpendicular to the direction of energy transport. Examples of transverse waves include electromagnetic waves like light and water waves.
How does light travel when the medium it travels through changes and how does light travel when the medium does not change?
When light travels through a medium with a different refractive index, its speed changes and it can bend or refract. In a medium where the refractive index does not change, light continues to travel in a straight line at a constant speed unless it encounters a different medium where it may reflect or refract.
Which type of wave causes the medium to vibrate perpendicular to the direction of the wave?
Transverse waves cause the medium to vibrate perpendicular to the direction of the wave. Examples of transverse waves include light waves and electromagnetic waves.
Does water refract or reflect light?
Water can both refract and reflect light. When light travels from one medium to another in water, it bends due to the change in speed, which is known as refraction. Additionally, light can also reflect off the surface of water, creating a reflection.
What happens when light is falling perpendicular by to an interface of two media?
When light falls perpendicular to an interface of two media, it continues to travel in a straight line without changing direction. There is no change in the speed or wavelength of the light. This phenomenon is known as normal incidence.
Does white light reflect or bend?
White light can both reflect and bend. When white light hits a smooth surface, it will reflect off the surface at the same angle it hit it. When white light passes through a different medium like glass, it will bend due to refraction.
