Technically, light does not "bend", but it can appear to do so. There are three principles involved - reflection, refraction, and diffraction.
.
In reflection, a beam of light strikes a surface, such as a mirror, and is then reflected, or bounced, away. The angle of incidence (the angle between the incoming light beam and the reflective surface) is always equal to the angle of reflection (the angle between the outgoing light beam and the same reflective surface).
.
When light strikes a non-opaque material perpendicular to the material's surface, then the light continues straight through the medium, or it is reflected back out the same direction. In most cases, some of the light is transmitted through the material, some is reflected, and some is attenuated (absorbed) while passing through the material.
.
When light strikes a non-opaque medium with an angle of incidence of less than 90o, some of the light will refract, which in every day experiences means to bend. As the light passes through the boundary from one medium into another medium, the speed of the light changes, and this change in light speed causes refraction, or bending. The amount by which light refracts, or bends as it crosses a medium boundary, is dependent only upon the difference of the refractive index between the two media.
.
As above, some of the incident light might reflect off the surface, some might be attenuated by the medium, and the remainder refracted light will be transmitted through the medium. Spherical lenses use refraction to magnify images. By controlling the curvature and refractive index of the lens medium, the lens maker can arbitrarily choose how much the lens bends, or focuses, incoming light.
.
Light can also be refracted by gravity sources, such as large stars or a black hole. Cosmologists call this "gravity lensing". While the light itself doesn't "bend", the space that the photons of light are passing through is warped by the gravity from a nearby black hole
.
If an obstacle of size about the wave length of light is placed along the path of the ray of light it will bend around the edges of the obstacle. This phenomenon is called Diffraction.
What else can I help you with?
Why does light bend when it enters a new medium?
Light changes speed and direction when it enters a new medium due to the change in the medium's refractive index, which is a measure of how much light slows down in the material. This change causes the light to bend because the speed of light is different in each medium it travels through.
How does material bend light?
Materials can bend light through a process called refraction. This occurs when light passes through a medium with a different density, causing its speed to change. The change in speed results in the light ray bending as it enters the new medium.
Is it true or false that light can be bent or refracted when it hits a new material at an angle?
True. When light enters a new material at an angle, it can bend or refract due to the change in the optical density of the medium. This phenomenon is known as refraction and is governed by Snell's Law.
What happens to light as it enters a new material?
When light enters a new material, it may be absorbed, transmitted, or reflected depending on the properties of the material. Some of the light may also be refracted, which causes the light to change direction as it enters the new material. The speed of light may also change, which can lead to phenomena such as dispersion.
Does the light reflect towards or away from the normal when it travels from low to high refractive index?
When light travels from a low to a high refractive index material, it will reflect towards the normal. This is due to the change in speed of light as it enters a new material, causing it to bend towards the normal line at the interface.
Will light bend when it enters new material?
Yes. Many solutions have unique refractive indeces. Refraction is the concept.
Why does light bend when it enters a new medium?
Light changes speed and direction when it enters a new medium due to the change in the medium's refractive index, which is a measure of how much light slows down in the material. This change causes the light to bend because the speed of light is different in each medium it travels through.
Will light bend if it enters a new material?
Yes. It depends on the angle of incidence and the details of refractive index of materials.

Will light always bend when it changes medium?
Not always. It won't bend if it enters the new medium perpendicular to the surface that separates them, and it won't bend when the refractive indices of the two media are equal.
Bending of light when it changes media is called?
Refraction
When light waves enter a new medium and bend what occurs?
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.
When light enters a new material will it reflects?
No how I think of it is it is like a rag it does not soak up right away it slower enters the fabric and then is wet
Why do light refract when hitting a glass or lens?
When light enters a different medium, its speed changes due to the change in optical density, causing the light rays to bend. This bending is known as refraction. The degree of bending depends on the angle at which the light enters the new medium.
