An example of wavelength is the distance between consecutive peaks or troughs of a wave. Wavelength is a fundamental property of waves and is usually represented by the Greek letter lambda (λ). It is commonly measured in meters (m) or other units of length.
To illustrate, consider the example of an ocean wave. As you observe the ocean, you can see sets of waves coming towards the shore. The wavelength of these waves refers to the distance between two adjacent wave crests (the highest points of the wave) or two adjacent wave troughs (the lowest points of the wave). You can measure this distance, and it will give you the wavelength of the ocean waves.
Another example can be found in the context of electromagnetic waves. Visible light, which is a type of electromagnetic wave, consists of different colors with varying wavelengths. For instance, red light has a longer wavelength compared to blue light. The wavelength of visible light determines its color when it interacts with our eyes.
In summary, the wavelength of a wave represents the spatial distance between two consecutive peaks or troughs and is applicable to various types of waves, including ocean waves, sound waves, and electromagnetic waves like visible light.
