## Top best answers to the question «What is the speed of a wave in water»

If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is **2.0 m/s**. On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s.

In the case of a wave, the speed is **the distance traveled by a given point on the wave (such as a crest) in a given interval of time**. In equation form, If the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s.

- The speed of sound in water is
**around 3,170 mph**, while the speed of sound in air is only**about 740 mph**. At room temperature, which is equivalent to 68 degrees, acoustic waves travel in water and air at speeds of**3,315 mph and 767 mph**, respectively.

#### What is the speed of sound in water?

- The speed of sound can also be affected by temperature. Sound waves tend to travel faster at higher temperatures. I have found different values for the speed of sound in water in different sources. They range from
**1450 to 1498 meters per second**in distilled water and 1531 m/s in sea water at room temperatures (20 to 25 °C).

- The
**depth of water**affects the speed of these waves directly without having anything to do with the density of the water. The deeper the water, the faster the waves travel, and so waves will refract (change direction) when they enter deeper or shallower water at an angle. ← 42. Waves across a boundary 44.

**Speed = Wavelength x Wave Frequency**. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

Because deep-water waves do not interact with the ocean bottom as they travel, their speed is independent of the water depth. But as waves enter shallow water, interaction with the bottom alters the waves. **Wave speed decreases, wavelength shortens and wave height increases**.

### Video answer: Gcse physics - water waves - shallow to deep water

What changes wave speed?- The amplitude of a wave does not affect the speed at which the wave travels. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by
**alterations in the properties of the medium through which it travels**.

The speed of a wave depends on the medium it is traveling through.

#### How to calculate 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…- The equation for wave speed can be written to solve for wavelength or frequency if the speed and the other value are known.

### Video answer: How to calculate wave speed - gcse physics

What effects wave speed?- The
**speed**of most waves depends on the medium in which it travels. Generally, waves travel fastest through solids and slowest through gases. This is because particles are closest together in solids and farthest apart in gases.

Summary. 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.

- The amplitude of a wave
**does not affect the speed at which the wave travels**. Both Wave A and Wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels. 2. The teacher then begins introducing pulses with a different wavelength.

- Solution: For all periodic waves v = λ/T = λf. The wavelength λ is 3 m. The speed is v = λf = (3 m) (4/s) = 12 m/s. Suppose that a water wave coming into a dock has a speed of 1.5 m/s and a wavelength of 2 m.

- The wavefoil moves at a speed between 4.5m and 7.5m (14.7ft-24.6ft) per second along the central channel under the pier, displacing water to form a glassy swell.” Once the swell is pushed out it interacts with the shallows of the lagoon to form the wave we see today.

- Reflection of water waves can be demonstrated using a ripple tank. Waves change speed when they pass across the boundary between two different substances, such as light waves refracting when they pass from air to glass. This causes them to change direction and this effect is called refraction.

Count the number of waves passing a point in ten seconds then divide by ten to record frequency. Calculate the speed of the waves using: **wave speed = frequency × wavelength**.

**Speed = Wavelength x Wave Frequency**. In this equation, wavelength is measured in meters and frequency is measured in hertz (Hz), or number of waves per second. Therefore, wave speed is given in meters per second, which is the SI unit for speed.

How is the speed of a shallow water wave determined?- A shallow water wave’s speed is dependent on ocean depth. Wave refraction. If part of a wave is in shallower water then it will travel slower. A shallow water wave’s speed is dependent on ocean depth.

Count the number of waves passing a point in ten seconds then divide by ten to record frequency. Calculate the speed of the waves using: **wave speed = frequency × wavelength**.

#### Why is the speed of sound faster in solids?

- If
**the**molecules are closer together then**the**sound can travel between them more easily and quickly. If**the**molecules are further apart and less tightly bonded then it is harder for**the**sound**to**travel and as a result the sound travels slower. This is**why the speed**of sound is faster in solids than in liquids and gases.
