Light Lecture Review

Flashcards covering key concepts about the behavior of light, including wave and particle behaviors, reflection, refraction, diffraction, interference, polarization, electromagnetic energy, and the photoelectric effect.

__ – bouncing of light

Reflection

Angle of incidence = angle of __

reflection

__ – bending of light

Refraction

Change in path due to change in __

speed

__ – spreading out of light

Diffraction

__ – Constructive or destructive

Interference

__ – light waves vibrating in one plane only

Polarization

Light from sun is __-polarized

non
