Waves: Diffraction

The video tutorial explains the concept of diffraction, illustrating how it allows sound to be heard around obstacles. It uses examples such as water waves reforming behind objects and sound traveling around buildings to demonstrate how diffraction works in different scenarios.

What phenomenon allows you to hear sounds like a horn even when there are obstacles?

• Diffraction

• Absorption

• Refraction

• Reflection

When observing waves in water, what happens to the waves behind an obstacle?

• They reform

• They become larger

• They stop moving

• They disappear

Which of the following is an example of diffraction?

• Light bending through a prism

• Sound heard around a corner

• A mirror reflecting an image

• A lens focusing light

What is the term for the bending of waves around obstacles?

• Transmission

• Diffraction

• Reflection

• Scattering

In the context of the video, what is the significance of the brick building?

• It blocks sound completely

• It reflects sound waves

• It absorbs sound waves

• It demonstrates diffraction
