Properties of Light

Light travels in a ______ line until it comes in contact with an object. Then, it is then either reflected, transmitted, or absorbed.

What happens when light is reflected?

• Light goes into the object and stops.

• Light bounces off the object.

• Light passes through the object.

What does it mean when light is transmitted?

• Light bounces off the object.

• Light can pass through the object.

• Light goes into the object and stops.

Absorbed: Light goes ______ the object and ______.

• into, stops

• around, continues

• through, reflects

• over, disappears

Law of reflection: The light ray that hits an object's surface is called the ______ ray. The reflected light ray is called the ______ ray. The angles they create are always ______.

• incidence, reflection, equal

• reflection, incidence, opposite

• incident, refracted, different

• refracted, incident, similar

According to the law of reflection, the angles of incidence and reflection are always:

• Different

• Equal

• Greater than 90 degrees

• Less than 45 degrees

How do we see? We are able to see non-luminous objects because light ______ off an object and goes to our ______.

• reflects, eyes

• absorbs, hands

• refracts, nose

• emits, ears

We are able to see non-luminous objects because light reflects off an object and goes to our eyes.

• True

• False

Refraction: When ______ travels through two mediums with different densities it 'bends', or refracts. The light slows down as it passes through the thicker medium. Fill in the blank.

• light

• sound

• heat

• electricity

When light hits water it slows down because water is ______ dense than air.

• more

• less
