Exploring the Reflection of Light

What is the Law of Reflection?

• The angle of incidence equals the angle of reflection.

• The angle of reflection is twice the angle of incidence.

• The angle of incidence is equal to the angle of refraction.

• The angle of incidence is always greater than the angle of reflection.

Define the angle of incidence and angle of reflection.

• The angle of incidence is always greater than the angle of reflection.

• The angle of incidence is half of the angle of reflection.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence and angle of reflection are unrelated.

What are the 3 main types of mirrors?

• Circular, triangular, and hexagonal mirrors

• Reflective, refractive, and absorptive mirrors

• Plane, concave, and convex mirrors

• Opaque, transparent, and translucent mirrors

Which ray is from the light source?

• Normal

• Reflected ray

• Incident ray

• Angle of Incidence

Identify the type of mirror in the illustration.

• Convex mirror

• Concave mirror

• Plane mirror

• Round mirror

How do concave mirrors differ from convex mirrors?

• Convex mirrors focus light and can create real images, while concave mirrors do not.

• Concave mirrors always produce virtual images, while convex mirrors can form real images.

• Concave mirrors focus light and can form real images, while convex mirrors always produce virtual images and provide a wider field of view.

• Concave mirrors provide a wider field of view, while convex mirrors focus light.

Describe one application of concave mirrors.

• Magnifying glasses

• Solar panels

• Flat screen TVs

• Reflecting telescopes.

What happens to light when it reflects off a smooth surface?

• Light is absorbed completely by the surface.

• Light scatters in multiple directions upon hitting the surface.

• Light reflects off a smooth surface at an angle equal to the angle of incidence.

• Light passes through the surface without any change.

Explain how reflection occurs in water.

• Reflection occurs in water when light waves strike the surface, causing some light to bounce back.

• Reflection in water occurs when sound waves hit the surface.

• Reflection happens in water due to the absorption of light by the water molecules.

• Reflection is caused by the movement of water creating ripples that distort light.

What is the significance/importance of the normal line in reflection?

• The normal line is used to measure the distance of reflection.

• The normal line indicates the speed of light in a medium.

• The normal line determines the color of the reflected light.

• The normal line defines the angles of incidence and reflection, which are equal.
