# What is the frequency of a wave that has a speed of 0.4 m/s and a wavelength of 0.020 meter?

What is the frequency of a wave that has a speed of 0.4 m/s and a wavelength of 0.020 meter? 20 hertz. Many wave properties are dependent upon other wave properties.

## 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 determines the speed of any wave?

Waves and Energy: The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f). Certain conditions make the following calculations easy. speed is constant in a given medium.

## 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.

## 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 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 SI unit of frequency?

The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz).

## What is the highest point of a wave?

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 is the frequency of a pendulum vibrating 40 times in 20 seconds?

8.00 x 102 Hz. The period is the time for one complete cycle. If the pendulum takes 20.0 seconds for exactly 40 vibrational cycles, then it must take 0.500 second for one cycle.

## What is the formula for wave?

The constant velocity of a wave can be found by v=λT=ωk. v = λ T = ω k .

## What type of wave is sound?

Longitudinal waves A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave. Sound waves are longitudinal waves. When longitudinal waves travel through any given medium, they also include compressions and rarefactions.

## Does sound travel faster in air or water?

While sound moves at a much faster speed in the water than in air , the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.

## 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 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 travels on a wave?

What travels on a wave? Energy travels on a wave. The waves carry the energy along without transporting matter from place to place.

## What are the 3 parts of a wave?

Wave Crest: The highest part of a wave. Wave Trough: The lowest part of a wave. Wave Height: The vertical distance between the wave trough and the wave crest.

## 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.

## What are 2 types of surface waves?

The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them. Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love waves move faster.

## What type of wave is light?

1. 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.

## Is light a plane wave?

Light is a transverse electromagnetic wave, but natural light is generally unpolarized, all planes of propagation being equally probable. If light is composed of two plane waves of equal amplitude by differing in phase by 90°, then the light is said to be circularly polarized.

## How are waves formed?

Waves occur when the force of the wind blows over surface water, transferring its energy and causing the water to move in a circular motion. The rise and fall of water molecules creates a wave that moves in the direction of the wind.

## Where will sound travel fastest?

Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster. Sound travels most slowly through gases because the molecules of a gas are farthest apart.
