Reflect Refract Absorb

Front

What is reflection in terms of light?

Back

Reflection is the bouncing back of light rays when they hit a surface that does not absorb the light. For example, a mirror reflects light.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air into water. This bending causes objects to appear distorted.

Front

What is absorption in the context of light?

Back

Absorption is the process by which light is taken in by a material, converting it into other forms of energy, such as heat. For example, a black surface absorbs more light than a white surface.

Front

How does the color of an object relate to light absorption and reflection?

Back

The color of an object is determined by the wavelengths of light it reflects. For instance, a red object reflects red light and absorbs other colors.

Front

What happens to light when it passes through glass?

Back

Light usually passes through glass, which means it is transmitted rather than absorbed or reflected.

Front

What causes shadows to change during the day?

Back

Shadows change due to the sun's position in the sky, which alters the angle and length of the shadow.

Front

What is a prism and how does it relate to light?

Back

A prism is a transparent optical element that refracts light, separating it into its component colors, creating a spectrum.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different media.

Front

What is the significance of the angle of incidence in reflection?

Back

The angle of incidence is the angle at which incoming light strikes a surface. According to the law of reflection, the angle of incidence equals the angle of reflection.

Front

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.
