What is the cause and effect relationship between frequency and wavelength?
In a given medium under fixed conditions, vw is constant, so that there is a relationship between f and λ; the higher the frequency, the smaller the wavelength.
Why does frequency decrease as wavelength increases?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
What is the relationship between frequency and wavelength?
Wavelength and frequency are two such characteristics. The relationship between wavelength and frequency is that the frequency of a wave multiplied by its wavelength gives the speed of the wave, as we will see below.
Why does a wave have a high frequency?
(A) A wave consists of alternation crests and troughs. The wavelength (λ) is defined as the distance between any two consecutive identical points on the waveform. The amplitude is the height of the wave. (B) A wave with a short wavelength (top) has a high frequency because more waves pass a given point in a certain amount of time.
How do you find the frequency of a wave?
Convert the wavelength to m, then apply the equation c = λν and solve for frequency. Dividing both sides of the equation by λ yields: Step 3: Think about your result. The value for the frequency falls within the range for visible light. All waves can be defined in terms of their frequency and intensity.
How does an alteration in the wavelength affect the wave speed?
Even though the wave speed is calculated by multiplying wavelength by frequency, an alteration in wavelength does not affect wave speed. Rather, an alteration in wavelength affects the frequency in an inverse manner. A doubling of the wavelength results in a halving of the frequency; yet the wave speed is not changed.
