Why the observed frequency is greater than the frequency of the source?
The observed frequency can be greater than the frequency of the source due to the Doppler effect, where the relative motion between the source and observer causes a shift in the frequency of the wave. When the source is moving towards the observer, the observed frequency is higher, and when the source is moving away, the observed frequency is lower.
If a wave has amplitude of 0.2 meters a wavelength of 0.5 meters and a frequency of Hz at what speed is it moving?
The speed of a wave is given by the formula speed = frequency x wavelength. Substituting the given values, the speed of the wave would be 0.25 m/s (1 Hz x 0.5 m).
What is the frequency of a sound wave moving in air at room temperature if the wavelength is 78 meters?
The speed of sound in air at room temperature is approximately 343 m/s. To find the frequency, you can use the formula: frequency = speed of sound / wavelength. So, the frequency of a sound wave with a wavelength of 78 meters in air at room temperature would be 343 m/s / 78 m = around 4.4 Hz.
What is a term that describes crests and troughs of light waves moving in phase?
Light waves with the same phase and frequency are said to be coherent.
Which are the four properties that all waves have?
The four properties that all waves have are amplitude (height of the wave), wavelength (distance between two consecutive points), frequency (number of waves passing a point in a given time), and speed (how fast the wave is moving).
How fast is a wave moving if its wavelength is 10meters and its frequency is 110Hz?
The speed of a wave is equal to its wavelength times its frequency. Since you are using SI units, the answer will be in meters/second.
What is the frequency of a sound wave moving in a room temperature if the wavelength of 0.686 meters?
The speed of sound varies with temperature. At commonly experienced temperatures, it's about 343 meters/sec. Frequency = speed/wavelength = 343/0.686 = 500 Hz
Why the observed frequency is greater than the frequency of the source?
The observed frequency can be greater than the frequency of the source due to the Doppler effect, where the relative motion between the source and observer causes a shift in the frequency of the wave. When the source is moving towards the observer, the observed frequency is higher, and when the source is moving away, the observed frequency is lower.
If a wave has amplitude of 2 meters a wavelength of 2 meters and a frequency of 10 Hz and a period of 1 second then at what speed is the wave moving?
speed = distance over time = wavelength times frequency = 2 m times 10 hz = 20 m hz = 20 meters per second.
How fast is a wave moving if its wave length is 10 meters and its frequency is 110 Hz?
The formula for a wave in this case is: speed = frequency x wavelength. Since Hz = 1/second, the answer will be in meter/second.

The speed of a wave is given by the formula speed = frequency x wavelength. Substituting the given values, the speed of the wave would be 0.25 m/s (1 Hz x 0.5 m).

What is weston frequency meter?
Weston frequency meter is a type of electromechanical instrument used for measuring the frequency of an alternating current (AC) power system. It typically consists of a moving-coil meter mechanism that reacts to the frequency of the AC signal to provide a reading on its scale. Weston frequency meters are used in various applications to monitor and analyze the frequency of electrical systems.
Which are the four properties that all waves have?
The four properties that all waves have are amplitude (height of the wave), wavelength (distance between two consecutive points), frequency (number of waves passing a point in a given time), and speed (how fast the wave is moving).
What is the observed change in the frequency of a wave when either the source or observer is moving?
When either the source or the observer is moving, there is a change in the frequency of the wave observed, known as the Doppler effect. If the source is moving towards the observer, the frequency appears higher (blueshift); if the source is moving away, the frequency appears lower (redshift). The same principle applies if the observer is moving instead of the source.
If a vacuum has a frequency of 1.01000000000000000000 what is the wave length?
Vacuums don't have frequencies.Electromagnetic waves moving through vacuums have frequencies and wavelengths.They also have speed. Regardless of their frequency and wavelength, their speed is always299,792,458 meters per second.The wavelength of an electromagnetic wave is [ (its speed) divided by (its frequency) ].If its frequency is 1.01 Hz, then its wavelength is 296,824,215.8 meters (about 184,438 miles).
