Exploring Light Reflection

What is the Law of Reflection?

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

• The angle of incidence equals the angle of reflection.

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

• The angle of incidence and reflection are both 90 degrees.

State the angle of incidence in relation to the 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 is perpendicular to the angle of reflection.

What happens to light when it hits a smooth surface?

• Light passes through a smooth surface.

• Light reflects off a smooth surface.

• Light scatters in all directions.

• Light absorbs into a smooth surface.

Give an example of a real-life application of reflection.

• Using mirrors to create a funhouse effect in amusement parks.

• Reflecting sound waves in a concert hall for acoustics.

• Solar panels using mirrors to reflect sunlight.

• Using reflective paint to enhance road visibility at night.

How does a mirror utilize the Law of Reflection?

• A mirror bends light instead of reflecting it.

• A mirror absorbs light without reflection.

• A mirror utilizes the Law of Reflection by reflecting light at equal angles of incidence and reflection.

• A mirror reflects light only at 90-degree angles.

What is the angle of incidence if the angle of reflection is 30 degrees?

• 60 degrees

• 30 degrees

• 15 degrees

• 45 degrees

Describe how reflection is used in periscopes.

• Reflection in periscopes involves using a single curved lens to focus light.

• Reflection is used in periscopes by employing two mirrors to redirect light from an object to the viewer's eye.

• Periscopes use reflection by capturing sound waves instead of light.

• Reflection is used in periscopes by bending light through a prism.

What type of surface would cause diffuse reflection?

• Polished metal surfaces

• Rough or uneven surfaces

• Transparent water surfaces

• Smooth glass surfaces

Explain why we can see our reflection in water.

• We can see our reflection in water because it absorbs all light.

• We can see our reflection in water because light reflects off the smooth surface of the water.

• We can see our reflection in water due to the color of the water.

• We can see our reflection in water because it is a solid surface.

How does the angle of incidence affect the brightness of a reflected image?

• All angles of incidence produce the same brightness.

• The angle of incidence has no effect on brightness.

• Steeper angles always increase brightness.

• The angle of incidence affects brightness; shallower angles increase brightness, while steeper angles decrease it.
