Light and Sound Assessment

What is the primary way that light travels?

• In curved paths

• In straight lines

• In zigzag patterns

• In circular motions

Which type of object produces its own light?

• Mirror

• Moon

• Light bulb

• White paper

What happens when light hits a transparent material?

• All light is absorbed

• All light is reflected

• Most light passes through

• All light is scattered

What is a non-luminous object?

• An object that produces its own light

• An object that reflects light from other sources

• An object that creates energy

• An object that generates heat

When light changes direction as it passes from one medium to another, this is called:

• Reflection

• Absorption

• Refraction

• Diffraction

What type of mirror creates an upright, smaller image?

• Convex mirror

• Flat mirror

• Concave mirror

• Curved mirror

Why is the Sun considered Earth's main source of natural light?

• Because it's the closest star

• Because it generates its own light through nuclear fusion

• Because it reflects light from other stars

• Because it's the largest star

Which material would be best for making a mirror?

• Wood

• Plastic

• Glass with a reflective coating

• Paper

What happens during reflection?

• Light bends when entering a new medium

• Light bounces off a surface

• Light is absorbed completely

• Light spreads out in all directions

How do convex lenses affect light rays?

• They spread light rays apart

• They block all light rays

• They bring light rays together

• They reflect all light rays
