ACOD WS1 Light and Spherical Quiz

The colour of an object is the result of

• Absorption and reflection

• Refraction and transmission

• Reflection and refraction

• Refraction and transmission

When a customer tells us they spend a lot of time fishing and skiing, we should recommend

• 
  

  A graduate tint

• 
  

  A glass lens

• 
  

  A polarising filter

• A high index lens

Refractive index is a measure of

• Lens thickness

• Lens size

• Lens density

• Lens weight

Refraction is

• The bending of light as it passes from one optical medium to another

• Light bouncing off a surface

• Similar to a mirror effect

• The bending of light inside an optical medium

The symbol that represents refractive index is

• D

• Ration

• F

• n

Converging light will

• Eventually make a focal point

• Be very bright

• Never pass through a lens

• Never make a focal point

Total internal reflection can only occur when

• The weather is right

• The light is inside the optical medium

• The light is outside the optical medium

• The critical angle is larger than the angle of incidence

The benefit of a polarising filter is

• All light is blocked

• All reflected light is blocked

• 
  

  All polarised reflected light is transmitted

• 
  

  All polarised reflected light is blocked

Diffuse reflection involves

• Light bouncing off a surface at multiple different angles

• Light bouncing continually within a material

• Light spreading apart

• Light bouncing off a surface at the same angle at which it struck the surface

When light passes from air into an optical medium, it will always

• Reflect towards the normal

• Refract away from the normal

• Refract towards the normal

• Reflect away from the normal
