Show hintHide hint
Think about how light changes when it enters a new medium.
Question 2.
What type of lens is used to correct myopia?
Show hintHide hint
Think about how different curves of lenses affect vision.
3Question 3.
What happens to light when it enters a denser medium?
- It speeds up
- It slows down
- It stays the same
Show hintHide hint

4Question 4.
True or False: Concave lenses are used to magnify objects.
- True
- False
Show hintHide hint
Think about the shape of the lens and its purpose.
Question 5.
A scientist wants to design a lens that can correct both myopia and hyperopia. Explain the different lens types required and how they adjust focal lengths.
Show hintHide hint
Consider how each lens type affects light differently.
Question 6.
Calculate the angle of refraction when light passes from air (n=1.00) into glass (n=1.5) at an incidence angle of 30 degrees. Use Snell's Law.
Show hintHide hint
Remember to use Snell's Law with refractive indices and angles.
