Frequency is the number of cycles per second represented in Hertz (Hz). The wavelength is the measure of the length of the wave (measured from peak to peak most commonly). In optics, wavelength determines the color of light, where frequency places it where it belongs in the electro-magnetic spectrum (i.e. infrared, ultraviolet, or visible to human eye).
What else can I help you with?
What is difference between frequency polygon and line graph?
The difference between frequency polygon and line graphs is their purpose. Frequency polygons are for understanding shapes distributions, while line graphs shows information that is related in some way.
What is the Difference in relative frequency and percentage frequency?
Relative frequency is a method of calculating the frequency of an event. Percentage frequency is a way of presenting the frequency of an event.
How are the pieces of a pie chart related to relative frequency?
The pieces of a pie chart represent the parts of a whole, as does relative frequency. The total of the entire pie chart should be 100% or 360 degrees. The sum of the relative frequencies should also equal 100%.
What is the equation for frequency density?
frequency density = frequency/group width
Suppose that a frequency histogram and a cumulative frequency histogram are constructed from the same set of data using the same classes is the frequency for each class is the frequency equal to the?
the frequency is less than OR EQUAL TO the cumulative frequency
What are wavelenghts?
wavelenght is the distance between the 2 peaks in sound waves and can be calculated by Wavelenght is = wave speed/ frequency or wave speed __________ frequency
What does increasing the wavelength of an electromagnetic wave decrease?
Increasing the wavelength of an electromagnetic wave decreases its frequency. This is because wavelength and frequency are inversely related in electromagnetic waves, as described by the equation λν = c, where λ is wavelength, ν is frequency, and c is the speed of light.
What does wavelenght tell about frequency?
Wavelength and frequency are inversely related in a wave. A shorter wavelength corresponds to a higher frequency, while a longer wavelength corresponds to a lower frequency. This relationship is described by the formula: speed = wavelength x frequency, where speed is a constant for a given medium.
What is the mathematical relationship between frequency wavelenght and wave speed?
Speed = frequency x wavelength.
What are the definitions of amplitude frequency and wavelenght?
Speed c of the wave in the medium = frequency ftimes wavelength lambda.
What is the wavelenght of a wave related to?
distance
Why can you see objects in different colours?
It all depends on the frequency of a wavelenght for example red is a low frequency and violet is a high frequency
What if your answer If a sound has a high pitch then it has a frequency and therefore a wavelenght?
Yes, a sound with a high pitch has a high frequency, which means it has a shorter wavelength. The pitch of a sound is directly related to its frequency, with high-pitched sounds having higher frequencies and shorter wavelengths.
How to calculate the frequency of an electromagnetic wave you need to know the speed of the wave and its?
You need to know it speed, wavelenght and its frequency.
How coud you find the wavelenght of light you knew its speed and frecucey?
wavelength = velocity / frequency
Do sound waves have wavelenght?
Yes. The wavelength of a sound is(speed of sound in air)/(frequency of the sound) .
When sound wave refracted from air to water what will remain unchanged?
The frequency of the sound wave will remain unchanged when it refracts from air to water.
