When light strikes a surface
100
What is Refraction?
The bending of light as it passes from one medium to another.
100
Name a law of refraction.
When light travels from one medium(material) to another, it generally bends, or refracts.
Answers may vary.
100
When can refraction occur?
Refraction can occur when light travels through different temperatures pr densities.
100
What happens to light when it strikes a surface?
Travels through the surface often in a new direction.
200
What is Density?
A measurement that compares the amount of matter an object as to it's volume.
200
Name a law of refraction.
The law of refraction gives us a way of predicting the amount of bend.
200
What is an example when refraction occurs?
ex. Refraction can also occur when light travels through the air at different temperatures.
200
What is the nature of surface?
Occurs when light strikes a different, transparent medium.

300
What is angle of refraction?
The angle made by a refracted ray with a perpendicular to the refracting surface.
300
What year was refraction discovered?
1621.
300
Why does mirage happen?
That's because the air on the ground is hotter and less dense than the air higher up.
300
What is another nature of surface?
Some light is usually reflected off the surface.
Answers may vary.
400
What is mirage?
An optical illusion caused by atmospheric conditions.
400
Who created the refraction law?
Willobrord Snell.
500
What is refract?
When an object or material creates a ray of light changing a direction when it enters an angle.

What is happening in this photo?
As the light is hitting the surface of water the refracted ray is bent.
