Test 1

Light bending as it passes from one medium (object) to another is...

• Refraction
• Reflection

How does light behave as it enters these mediums?

• continue its path as straight line.
• bends toward the normal
• bends away from the normal
• reflects

What is this image showing?

• Reflection
• Refraction
• The law of reflection
• Concave Mirror

Refraction is when light__________.

• Is bounced by an object or material.

• Changes speed as it travels in different materials which causes bending.

• When light speeds up to over 300,000 km/s

Light emerging from water to air will bend ______ due to the change of speed as it crosses the boundary.

• toward the normal

• away from the normal

• along the normal

Light travels through air, water, glass and many other materials. What path does it travel to get from one place to another?

• sideways

• back and forth

• straight

• up and down

When does the light is refracted?

• When light travels in a straight line

• When light is bounced

• When light travels in two different mediums

• When light cannot pass through an opaque object

What is the conclusion from your observation in this picture?

• Light travels in a straight line

• Light can be refracted

• Light can be reflected

• Light can pass through a transparent material
