Refraction

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

• Refraction
• Reflection

What form does light travel in?

• Curved line
• Zig-Zag
• Straight Line

Light bending as it passes through a rain drop is an example of...

• Refraction
• Reflection

What causes light to appear refracted?

• temperature
• speed
• weather
• climate

According to Willebord Snell, light passing from air to glass will cause the light to

• maintain its original speed 
• accelerate while it is in glass
• increase its speed
• reduce its speed

What is this called?

• refraction
• reflection
• reconstroction
• retraction

The velocity of light in vacuum is _______ ms^(-1)

• 3x10⁸
• 3x10¹²
• 3x10⁶
• 3x10¹⁰

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

Light changes speed as it travels through various mediums.  What are examples of mediums that light can travel through.

• snow and ice
• air and water
• cloth and wood
• glass and wood

Swimming pools and the ocean look shallower than they really are due to:

• reflection 
• dispersion
• refraction
• total internal reflection
