refection reflation diffraction

what is diffraction

• is a soild liquid gass

• is a beam of light that is spread out and passes through an object

• a beam of light

A wave of constant wavelength diffracts as it passes through an opening in a barrier. As the size of the opening is increased, the diffraction effects

• decrease

• increase

• remain the same

This image is representing what wave interaction?

• Refraction
• Diffraction
• Reflection
• Interference

What is the main difference between refraction and diffraction?

• refraction is a phenomenon that affects light; diffraction is a phenomenon that affects sound
• refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle
