Why do sound and light waves bend?

Since the wavelength of visible light is on the order of 0.5 microns, or 0.0005 mm, light will only diffract when going through very narrow openings. Sound waves, on the other hand, have a wavelength on the order of 1 meter and diffract very easily. This allows sound waves to bend around corners.

Why do waves have that shape?

Figure 10.13: Ocean waves are energy traveling through water. As wind blows over the surface of the water, it disturbs the water, producing the familiar shape of a wave.

Why is sound like a wave?

Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.

Are sound waves straight?

Sound waves normally travel in straight lines directly outwards from their source, but they do not always travel in that way. An object standing in the path of a sound wave can affect its movement. When a sound wave hits a hard object, the sound reflects back towards the source in the form of an ECHO.

Does sound bend like light?

For example, sound waves bend around corners much more than light does. That’s why you can hear but not see around corners. For a given type of waves, such as sound waves, how much the waves diffract depends on the size of the obstacle (or opening in the obstacle) and the wavelength of the waves.

Do waves have a shape?

Energy often travels in waves. Waves can take on many shapes. One of the most common wave shapes is called a sine wave, shown below. Light waves are one of many types of waves in nature shaped like sine waves.

What is the shape of an ocean wave?

The shape of an ocean wave is often depicted as a sine wave, but the the experimental waveshape is described as a “trochoid”. A trochoid can be defined as the curve traced out by a point on a circle as the circle is rolled along a line.

What is the difference between sound waves and water waves?

Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They’re also called longitudinal waves because the air vibrates along the same direction as the wave travels.
