# How are waves affected by moving from one medium to another such as air to water?

## How are waves affected by moving from one medium to another such as air to water?

The diagram shows that as a wave travels into a denser medium, such as water, it slows down and the wavelength decreases. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.

## How the behavior of waves is affected by medium?

The speed of a wave depends on the properties of the medium through which it travels. For example, sound travels much faster through water than through air. When a wave enters at an angle a medium through which its speed would be slower, the wave is bent toward the perpendicular.

How would you describe the behavior of as wave?

All waves behave in certain characteristic ways. They can undergo refraction, reflection, interference and diffraction. These basic properties define the behaviour of a wave – anything that reflects, refracts, diffracts and interferes is labelled a wave.

### What happens to a wave when it changes medium?

From this equation wavelength depends on the speed of the wave (i.e the medium) and the frequency; so it is different for different mediums. Think of frequency in the equation as a constant since it only depends on the source– so if now speed changes (i.e. medium changes), then only wavelength changes!

### What type of wave behavior occurs when a wave stays in the same medium but bends around an obstacle?

Diffraction occurs when a wave stays in the same medium, but bends around an obstacle. This can occur when the wave encounters a small object in its path or when the wave is forced through a small opening.

What describes the behavior of waves when they strike a surface?

Reflection occurs when waves bounce back from a surface they cannot pass through. When waves strike an obstacle head on, the reflected waves bounce straight back in the direction they came from. When waves strike an obstacle at any other angle, they bounce back at the same angle but in a different direction.

## What is a medium in Science waves?

Matter that waves are traveling through is called a medium. Sound waves cannot travel in the vacuum of space because there is no medium to transmit these mechanical waves. Classical waves transfer energy without transporting matter through the medium.

## How would the wave behave if it reflected off the medium?

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. So if the medium (and its properties) is changed, the speed of the waves is changed.

How do the behavior of waves help us hear?

The change in air-pressure moves the eardrum. When a sound wave travels down the ear canal, it pushes the eardrum back and forth. The movements of the eardrum are very small and since the inner ear conducts sound though a fluid, not a gas, the total pressure of the sound has to be increased.

### When a wave changes mediums partial reflection what happens?

What happens when a wave travels into a different medium? At the boundary between the two media, the speed and wavelength change, and some reflection occurs. This is called partial reflection because some of the energy is transmitted into the new medium and some is reflected back into the original medium.
