Because they travel at the same speed in a given medium, low-frequency sounds must have a greater wavelength than high-frequency sounds. Here, the lower-frequency sounds are emitted by the large speaker, called a woofer, while the higher-frequency sounds are emitted by the small speaker, called a tweeter.
Notice that this measure, wavelength, then depends not only on the speed of propagation of the wave, but also on the period (or frequency) of the vibration. Not only do waves behave very differently from material objects in the context of transmission of momentum and energy, but they also interact with each other differently than material ...
Jul 18, 2016 · So, as the frequency increases, the wavelength decreases - a doubling of frequency causes a halving of wavelength etc. Wavelength. As indicated in the diagram above, the wavelength of a cyclic curve is the distance between adjacent corresponding points - peak to peak, trough to trough etc.
The wavelengths of visible light are measured in nanometres, nm (billionths of a metre) but the equation works just the same. For example, red light has a wavelength of around 620 - 740 nm and blue light has a wavelength of around 445 - 500 nm. When we look at a light source the colours we see are dictated by the frequency of the light.
High School Physics Chapter 14 Section 1
In the same way, if we know the frequency, the wavelength will be equal to the speed of light between the frequency: For example, a radio wave of 3 m would have a frequency of 100 thousand hertz: v = 3 × 10 8/3 m = 100 000 000 Hz = 100 kHz (kilohertz)
For light, the relationship between wavelength (λ) and frequency (ƒ) is straightforward, their product is equal to the speed of the wave, which for light is (c ≈ 3.00 × 108 m/s).
