What are the waves of light and sound?
What are the waves of light and sound?
Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.
What terms are used to describe sound waves?
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength. That is it is the length of one complete wave.
What are the waves in light called?
Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That’s why light is called Electromagnetic Radiation.
What are the similarities and differences between light and sound waves?
Similarities
- light waves and sound waves can both be diffracted, reflected & refracted.
- they can both have a range of frequencies and wavelengths.
- they both transfer energy without transferring matter.
What are the two types of sound waves?
There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated.
What are the 2 general types of waves?
Waves come in two kinds, longitudinal and transverse.
What causes a light wave?
Photons are little packets of energy. When they hit an object, the energy transfers, exciting electrons in the object. If the photon contains the right amount of energy the bonds between atoms break. This is how light fades colors, weakens some materials and causes other damage.
How do we know light is a wave?
In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave. He passed a beam of light through two thin, parallel slits. The bright and dark bands demonstrated that the slits were causing light waves to interfere with each other.
How are sound waves and light waves used?
Sound waves and light waves carry energy that enable you to hear and see the world around you. Write a short paragraph describing water waves you have seen.

Which is an example of a wave with a basic characteristic?
Sound waves, light waves, X-rays, microwaves, and ocean waves are but a few examples. All waves, however, share certain basic characteristics.
How does the pitch of a sound wave depend?
The pitch of a sound depends on how fast the particles of a medium (the material through which a wave travels) vibrate. So the pitch of a sound depends on the number of waves produced in a given time.
Which is a high frequency sound and a low frequency sound?
Key point here: Sound waves that have a high frequency are heard as sounds of high pitch. A violin produces high-pitched sounds. Sound waves that have a low frequency are heard as sounds of low pitch. A tuba produces low-pitched sounds.
What are the waves of light and sound? Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. What terms are used to describe sound…
