Light-Refraction

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

According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

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

When a red light ray travels from air into a glass block, its

• velocity increases and its wavelength decreases 
• velocity decreases and its frequency stays the same
• velocity decreases and its frequency increases
• velocity remains the same and its wavelength decreases

We can see objects because of_______

• reflection
• refraction
• transmission
• diffraction
