What happens to light when it passes from one medium to another with a different density?
What happens to light when it passes from one medium to another with a different density?
- It always reflects back
- It gets absorbed by the medium
- It bends and changes its speed (correct)
- It always stays in its original form
What is true about the angle of incidence and reflection when light hits a mirror?
What is true about the angle of incidence and reflection when light hits a mirror?
- The angle of incidence is never related to the angle of reflection
- The angle of incidence is always less than the angle of reflection
- The angle of incidence is always greater than the angle of reflection
- The angle of incidence is always equal to the angle of reflection (correct)
What is the primary factor that determines how much light bends when it passes from one medium to another?
What is the primary factor that determines how much light bends when it passes from one medium to another?

Study Notes
Light and Reflection
- The angle of incidence from light hitting a mirror is equal to the angle of reflection.
Lenses
- No specific information provided about types of lenses.
Refraction
- Light bends when passing from one medium to another with a different density.
- The speed of light changes when passing from one medium to another, causing the light ray to bend.
- The bending of light occurs because of the change in speed, causing a change in the normal, straight path of the light ray.
Electromagnetic Spectrum
- No specific information provided about the electromagnetic spectrum.
Visible Spectrum of Light
- No specific information provided about the visible spectrum of light.
