- The Density of Medium: Sound requires a medium to travel. The density of the medium is among the factors which affect the speed of sound. …
- The Temperature of The Medium: Higher the temperature, the higher is the speed of sound in the medium.

Like any wave, the speed of a light wave is **dependent upon the properties of the medium**. In the case of an electromagnetic wave, the speed of the wave depends upon the optical density of that material. The optical density of a medium is not the same as its physical density.

Two main factors affect the speed of sound: **the material that makes up the medium—such as air or water—and the temperature**. If we know the medium and the temperature, however, we can predict the speed of sound.

Answer: Frequency and **wavelength are inversely proportional to each other**. The wave with the greatest frequency has the shortest wavelength.

Therefore, the relationship between f and λ is **inverse**: The higher the frequency, the shorter the wavelength of a sound wave.

velocity depends on **the frequency**, and, for a fixed wavelength , velocity will more if the frequency will be more, … velocity = frequency * wavelength, so, if frequency will increase, velocity will increase.

Tension determines the vertical force (perpendicular to wave motion) on molecules of string and hence determines the speed of perpendicular motion. Faster the perpendicular motion, faster the wave has passed by. Increasing the string tension effectively **reduces the remaining elastic capacity**.

But amplitude isn’t the only factor that affects the energy of a wave. **The other factor is frequency**. … So a wave of a particular amplitude will transmit more energy per second if it has a higher frequency, simply because more waves are passing by in a given period of time.

The speed of a wave on a string depends on **the linear density of the string and the tension in the string**. The linear density is mass per unit length of the string. In general, the speed of a wave depends on the square root of the ratio of the elastic property to the inertial property of the medium.

The speed of **light neither depends on the frequency or wavelength**. The speed of light is also independent of the velocity of the source. The speed of light is 3×108ms – 1.

As a result, **light** travels fastest in empty space, and travels slowest in solids. In glass, for example, light travels about 197,000 km/s. long a wavelength of light is? Wavelengths of light are usually expressed in units of nanometers (nm).
## Which has a lower frequency?

**Radio waves** have the lowest frequency.
## What will happen as the frequency of a wave increases and the speed remains constant?

## When frequency increases what happens to energy?

## What factors affect the speed of a wave Check all that apply quizlet?

If the speed of wave propagation remains constant, **an increase in the wavelength will result in a decrease in the frequency**.

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.

One factor that affects the speed of a wave is **the of medium**. Some waves move faster in solids and some waves move faster in liquids and gases. Another factor that affects wave speed is the of the medium. Frequency – number of wavelengths that pass a fixed point in a second.
