Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

TOWARDS or AWAY FROM. Light passes from glass to air.
bent away from the normal
What color is refracted through the largest angle?
violet
What color has the highest speed?
red
What is the order of colors in a spectrum?
ROYGBIV
This means the splitting of white light into different colors.
Dispersion
What is the law of reflection?
The law of reflection states that: angle of incidence i = angle of reflection r.
What is the angle of incidence when the angle of reflection is 35 degrees?
35 degrees
TRUE or FALSE. When the light passes through a glass from air, the angle of refraction is greater than the angle of incidence?
FALSE
TRUE or FALSE. Light travels faster in water than in glass.
TRUE
What is the relationship between angle of incidence and angle of refraction?
They are not equal, but when you increase angle of incidence, the light refracts more, so higher angle of refraction
What happens to the speed of light when it goes from a gas through a solid?
Denser medium, slows down, changes direction (refraction)
What happens to the speed of light when it goes from water to air?
it speeds up
What is 'r'?
Angle of reflection
What is 'i'?
Angle of incidence
What is C?
Reflected ray
What is B?
The normal
What is A?
Incident ray
What happens to light when it hits an smooth surface like mirror?
Light will be reflected
What happens to light when it hits a rough surface?
Rays of light are scattered
What happens to light when it hits a transparent surface?
It passes straight through

Glass is an example of which type of surface?
 
Transparent
 
Translucent
 
Opaque
What is the speed of light in air?
300 000 000 m/s
How are light rays drawn?
A straight line
