Reflexión

The transcript explains the concept of wave reflection, where waves return to their original medium after encountering a boundary. It highlights familiar examples like light reflecting off mirrors, glass, and water, and extends the concept to radio waves, sound waves that create echoes, and compression waves from earthquakes.

What happens to a wave when it encounters a boundary between two different media?

• It accelerates through the boundary.

• It reflects back to the original medium.

• It gets absorbed completely.

• It changes its frequency.

Which of the following is a common example of light reflection?

• Light being absorbed by a black surface.

• Light reflecting off a mirror.

• Light bending around corners.

• Light passing through a prism.

Which of these is NOT an example of wave reflection?

• Compression waves during an earthquake.

• Radio waves bouncing off the ionosphere.

• Light being refracted through water.

• Sound waves creating echoes.

What type of waves are responsible for creating echoes?

• Radio waves

• Sound waves

• Light waves

• Microwaves

Which waves are mentioned as being similar to light in terms of reflection?

• Gamma rays

• Infrared waves

• Radio waves

• Ultraviolet waves
