Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a wavelength?
A
How bright a lightbeam is
B
Distance from light source to the object the light strikes
C
Distance between two peaks on a wave of light
D
A single unit / “packet” of light
Explanation: 

Detailed explanation-1: -Wavelength is a measure of the distance between two successive peaks of a wave. It is usually measured in meters. The wavelength of a wave can be used to determine its frequency. The higher the frequency of a wave, the shorter its wavelength.

Detailed explanation-2: -For any wave, the wavelength is the distance between two consecutive peaks.

Detailed explanation-3: -The distance between two crests or compressions in a wave is called the wavelength. In a transverse wave the distance between two crests, or peaks, on the wave is the wavelength. Transverse waves move matter up and down, perpendicular to the movement of the energy.

Detailed explanation-4: -Electromagnetic waves are characterised by their wavelength () which is the distance between successive peaks and is measured in units of length, and by their intensity, or amplitude, which is the height of each of those peaks.

Detailed explanation-5: -wavelength| The distance between one peak or crest of a wave of light, heat, or other energy and the next corresponding peak or crest. amplitude| The height of a crest (or the depth of a trough) of a wave. frequency| Number of waves that pass a fixed point per unit time.
