The bending of light is called:

• reflection

• diffraction

• refraction

• dispersion

What type of lens is thinner in the middle than at the edges?

• Convex

• Concave

• Objective

• Magnifying

When light passes through a convex lens, it does this.....

• Diverge, or spread apart

• Converge, or come together

• Reflect, or bounce off

• Create a rainbow

What type of lens do you have in your eye?

• Concave

• Prismatic

• Objective

• Convex

The angle of the incoming rays of light are also called the.....

• Angle of reflection

• Angle of refraction

• Angle of incidence

• Wave angle

The thinner the convex lens, the ___________________ its focal length.

• Shorter

• Longer

• Thicker

• Thinner

T or F? Because the light rays never meet, a concave lenses can produce only a virtual image.

• True

• False

Which lens can produce images that are either smaller or larger than the object?

• a

• b

Which of the following is used to calculate the critical angle  :

• 
  $n_1\sin\left(\theta_1\right)=n_2\left(\theta_2\right)$
  

• $\frac{1}{f}=\frac{1}{x_i}+\frac{1}{x_0}$

• $\sin\theta_c=\frac{n_2}{n_1}$

• $m=\frac{h_i}{h_o}=-\frac{x_i}{x_o}$
