What is refraction of light?

Back

Refraction is the bending of light as it passes from one medium to another, causing it to change direction.

What is the process that produces an echo?

Back

An echo is produced by the reflection of sound waves off surfaces.

What is the relationship between amplitude and sound volume?

Back

Increasing the amplitude of a sound wave results in an increase in the volume of the sound.

What is a wavelength in terms of sound waves?

Back

A wavelength is the distance between two consecutive points of compression or rarefaction in a sound wave.

Front

What happens to light when it enters a denser medium?

Back

When light enters a denser medium, it slows down and bends towards the normal line.

What is the normal line in the context of light refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence where light strikes.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of waves when they hit a surface, while refraction is the bending of waves as they pass through different media.

What factors affect the speed of sound in a medium?

Back

The speed of sound is affected by the medium's density, temperature, and elasticity.

What is constructive interference in sound waves?

Back

Constructive interference occurs when two sound waves meet in phase, resulting in a louder sound.

Front

What is destructive interference in sound waves?

Back

Destructive interference occurs when two sound waves meet out of phase, resulting in a softer sound or cancellation.
