Study Jams - Light Absorption, Reflection & Refraction

Front

What is light absorption?

Back

Light absorption is the process by which materials take in light energy, converting it into other forms of energy, such as heat.

What is light reflection?

Back

Light reflection is the bouncing back of light waves when they encounter a surface that does not absorb all the light.

What is light refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

What factors affect light absorption in materials?

Back

Factors include the material's surface texture, color, and the wavelength of the light.

How does the roughness of a surface affect light reflection?

Back

Rough surfaces scatter light in many directions, leading to diffuse reflection, while smooth surfaces reflect light in a more uniform direction.

What is the angle of incidence?

Back

The angle of incidence is the angle between the incoming light ray and the normal (a perpendicular line) to the surface at the point of incidence.

What is the normal line in the context of light reflection and refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point where the light ray strikes.

What happens to light when it passes from air into water?

Back

When light passes from air into water, it slows down and bends towards the normal line, demonstrating refraction.

What is total internal reflection?

Back

Total internal reflection occurs when light attempts to move from a denser medium to a less dense medium at an angle greater than the critical angle, causing it to reflect entirely back into the denser medium.
