Diffraction

The video tutorial explains diffraction, a phenomenon observed in various waveforms such as light, radio, water, and subatomic particles. Diffraction becomes most noticeable when the gap through which the wave passes is small, comparable to the wavelength of the wave.

What is diffraction?

• A type of reflection

• A phenomenon where waves bend around obstacles

• A process of wave absorption

• A method of wave amplification

Which of the following is NOT a type of wave that can exhibit diffraction?

• Light waves

• Magnetic waves

• Sound waves

• Radio waves

Diffraction can be observed in which of the following?

• Only in water waves

• Only in light waves

• Only in sound waves

• In all types of waves

When is diffraction most noticeable?

• When the gap is much larger than the wavelength

• When the gap is much smaller than the wavelength

• When the gap is similar in size to the wavelength

• When there is no gap

What happens to waves when they pass through a small gap?

• They stop completely

• They get absorbed

• They reflect back

• They bend around the gap
