A
Wavelength (
B
Wavelength (
C
Wavelength () is measured in m/s
D
Wavelength () is measured in meters
Explanation: 

Detailed explanation-1: -It is denoted by the Greek symbol lambda ƛ. The standard unit of wavelength is metered (m).

Detailed explanation-2: -Units of Wavelength The SI unit of wavelength is meter because the wavelength is a measure of distance. As a measure of speed and distance, one meter is defined as the distance covered by light travelling in a vacuum in a duration of 1/ (3 x 10 8 ) seconds.

Detailed explanation-3: -In an equation, wavelength is represented by the Greek letter lambda (). Depending on the type of wave, wavelength can be measured in meters, centimeters, or nanometers (1m=109nm).

Detailed explanation-4: -Wavelength is usually denoted by the Greek letter lambda (); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): = v/f.
