What happens to the wavelength of light as its frequency increases?
What happens to the wavelength of light as its frequency increases?
- Wavelength increases
- Wavelength becomes irrelevant
- Wavelength decreases (correct)
- Wavelength remains constant
Which law describes how light reflects off a surface?
Which law describes how light reflects off a surface?
- Law of refraction
- Law of diffraction
- Law of dispersion

Which equation would you use to find the relationship between original and image heights in mirror calculations?
Which equation would you use to find the relationship between original and image heights in mirror calculations?
- $h_o/h_i = d_i/d_o$
- $h_i - h_o = d_i imes d_o$
- $h_i/h_o = d_i/d_o$ (correct)
- $h_i + h_o = d_i + d_o$

Flashcards
Refraction
Refraction
The bending of light as it passes from one medium to another. For example, light bending as it enters water from air.
Index of Refraction (n)
Index of Refraction (n)
The ability of a material to bend light. It's the ratio of the speed of light in a vacuum to the speed of light in that material.
Critical Angle
Critical Angle
A point beyond which a ray of light cannot be refracted (bent) back into the original medium. This occurs when light moves from a denser medium to a less dense medium.
