Wave Reflection, Refraction & Interference in Technology

Front

What is wave reflection?

Back

Wave reflection is the bouncing back of a wave when it hits a barrier or surface, allowing us to detect objects, such as in radar systems.

Front

How does wave reflection contribute to radar systems?

Back

Wave reflection helps radar systems determine the location of objects by reflecting radio waves off them.

Front

What is an echo?

Back

An echo is a sound that is reflected off a surface and heard again after a delay.

Front

What is wave refraction?

Back

Wave refraction is the bending of waves as they pass from one medium to another, changing their speed and direction.

How does wave refraction affect lenses in eyeglasses?

Back

Wave refraction allows lenses to focus light onto the retina, improving vision clarity.

What causes a rainbow to form when sunlight passes through water droplets?

Back

A rainbow forms because different colors in white light refract at different angles when passing through water droplets.

Front

What is the principle of interference in waves?

Back

Interference is the phenomenon that occurs when two or more waves overlap, resulting in a new wave pattern.

Front

What is the difference between constructive and destructive interference?

Back

Constructive interference occurs when waves combine to make a larger amplitude, while destructive interference occurs when waves combine to reduce amplitude.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles or through openings, which can affect how we perceive sound and light.

How does sound wave reflection help in navigation?

Back

Sound wave reflection is used in sonar technology to detect objects underwater by analyzing echoes.
