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?
The term is "constructive interference." This occurs when the peaks and troughs of two light waves align, resulting in a single wave with larger amplitude.
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.
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.

If a vacuum has a frequency of 1.01000000000000000000 what is the wave length?
In a vacuum, the speed of light is approximately 3.00 x 10^8 m/s. To calculate the wavelength, you can use the equation: wavelength = speed of light / frequency. Thus, the wavelength in this case would be approximately 2.97 x 10^8 meters.
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.
Does the frequency change if the observer moves?
Yes, the frequency of a wave changes if the observer is moving relative to the source of the wave. This is described by the Doppler effect, where the frequency appears higher if the observer is moving towards the source, and lower if the observer is moving away from the source.
The apparent change in the frequency of a sound emitted by a moving object?
The apparent change in the frequency of a sound emitted by a moving object is known as the Doppler effect. When the object is moving towards an observer, the frequency is perceived as higher (pitched up), and when the object is moving away, the frequency is perceived as lower (pitched down). This effect is commonly experienced with passing vehicles or sirens.
