# What is wave motion for class 6?

Wave motion is the transfer of energy and momentum from one point of the medium to another point of the medium without actual transport of matter between two points.

## What are the properties of waves answer key?

The basic properties of waves are amplitude, wavelength, frequency, and speed.

A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

## What is the frequency of a wave with a period of 0.005 seconds?

Thus, the frequency of the sound wave is 200 hertz.

## What are the 7 properties of waves?

There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below.

## What are 4 basic properties of waves?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. All waves can be thought of as a disturbance that transfers energy.

## What are 4 types of waves?

• Microwaves.
• X-ray.
• Ultraviolet waves.

## What are the 6 types of waves?

Usually, waves are around us, they can be sound waves, radio waves, water waves, sine waves, cosine waves, string waves, slinky waves, etc. These are created through disturbance. There are three types of waves.

## What are the 5 properties of waves?

• Property 1:Amplitude. The maximum displacement of the wave from the mean position is called the amplitude of the wave.
• Property 2: Frequency.
• Property 3: Wavelength.
• Property 4: Time Period.
• Property 5: Speed.

## Which sound wave has a higher pitch?

A higher frequency sound has a higher pitch, and a lower frequency sound has a lower pitch. In Figure 10.2 sound A has a higher pitch than sound B. For instance, the chirp of a bird would have a high pitch, but the roar of a lion would have a low pitch. The human ear can detect a wide range of frequencies.

## How is wave speed calculated?

Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength.

## What happen to the wavelength of a wave if frequency is doubled?

Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.

## What are the 3 types of wave motion?

• Mechanical Waves.
• Electromagnetic Waves.
• Matter Waves.

## What are the two main types of waves?

Waves come in two kinds, longitudinal and transverse. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves are like of those of sound, consisting of alternating compressions and rarefactions in a medium.

## What is the top of a wave called?

The highest part of the wave is called the crest. The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.

## What are 3 characteristics of waves?

Waves are disturbances that travel through a fluid medium. Several common wave characteristics include frequency, period, wavelength, and amplitude.

## What is a frequency of a wave?

In physics, the term frequency refers to the number of waves that pass a fixed point in unit time. It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

## What is the speed of a wave?

Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency.

## What are waves made of?

Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.

## Do all waves reflect?

Reflection is the bouncing back of a wave when it meets a surface or boundary that does not absorb the entire wave’s energy. All types of waves can be reflected. Reflections of sound waves, for example, are called echoes and help bats and dolphins learn about their environments.

## Why is amplitude important?

It is the distance between the crest or trough and the mean position of the wave. Loudness is directly proportional to the amplitude of the sound. If the amplitude of a sound wave is large, then the loudness of the sound will be more. If the amplitude is small, then the sound will be feeble.

## Which wave has the highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.

## What is the unit for frequency?

The SI unit for frequency is the hertz (Hz).

## What do waves carry?

To summarise, waves carry energy. The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.

## Which type of wave is light?

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light.
