Interactions of Light Waves

Multiple Choice

What is the difference between regular reflection and diffuse reflection?

• Both hit a smooth surface and reflect back the same way

• regular reflection hits a smooth surface and reflects back at the same angle; diffuse reflection hits a rough surface and reflects back at many angles

• diffuse reflection hits a smooth surface and reflects back at the same angle; regular reflection hits a rough surface and reflects back at many angles

• regular reflection and diffuse reflection are the same exact thing and there is no difference

Multiple Choice
