How many vibrations per second are associated with a 101-mhz radio wave?

How many vibrations per second are represented in a radio wave of 101.7 Mhz?

101.7 million vibrations

How many vibrations per second are there in a 100 Hz wave?

think! What is the frequency in vibrations per second of a 100-Hz wave? Answer: A 100-Hz wave vibrates 100 times/s.

How many times a wave vibrates in one second?

When we hear something, we are sensing the vibrations in the air. The number of vibrations per second is known as the frequency, measured in Hertz (1 Hz = 1 vibration per second). These vibrations enter the outer ear and cause the eardrum to vibrate too.

What happens if you double the frequency of a wave?

Doubling the frequency of a wave source (without altering the medium) doubles the speed of the waves. Don’t be fooled. … Yet doubling the frequency only halves the wavelength; wave speed remains the same. To change the wave speed, the medium would have to be changed.

What kind of waves can show interference?

Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves, gravity waves, or matter waves. The resulting images or graphs are called interferograms.

What is the relationship between frequency and pitch?

The pitch of a sound you hear depends on the frequency of the sound wave. A high frequency sound wave has a high pitch, and a low frequency sound wave has a low pitch.

What is wave period?

Wave period is the distance between two waves passing through a stationary point, measured in seconds.

What increases when a wave period decreases?

What increases when a wave period decreases. … Divide the wavelength by the wave period. As energy moves in waves through the water, the water moves. in a small circular movement.

What is the number of waves per second called?

The frequency ( ) of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz ( ), since one hertz is equal to one wave per second.

At what frequency do humans vibrate?

The important parts of the human body vibration frequency are generally located in about 3 Hz–17 Hz. According to the International Standard ISO 2631 in the vertical vibration of the human body, the sensitive range is located in 6 Hz–8 Hz.

Does a wave need a vibration?

Waves are a wiggle in space cause by a vibration or disturbance. They have the ability to carry energy from one location to another. There are two different types of waves; transverse and longitudinal. A transverse wave is when the wave is vibrating perpendicular to the direction the wave is traveling.

What can sound not travel through?


Does speed affect frequency?

The data convincingly show that wave frequency does not affect wave speed. An increase in wave frequency caused a decrease in wavelength while the wave speed remained constant. … Rather, the speed of the wave is dependent upon the properties of the medium such as the tension of the rope.

What happens when the frequency of a wave increases?

When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true—as frequency decreases, wavelength increases.
