Hint: Angstrom is used to express the wavelength. The wavelength is the distance between two wave crests, which is the same as the distance between two troughs. Formula: c = f where: c = the speed of light = 300,000 km/s or \[3.0 \times {10^8}m/s.\] = the wavelength of light, usually measured in meters or Angstroms( 1Å = \[{{10}^{ - 10}}m\]), f = the frequency at which light waves pass by, measured in units of per seconds (1/s).
Complete step by step answer:
Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire. In wireless systems, this length is usually specified in meters (m), centimeters (cm) or millimeters (mm).
Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
Here the Angstrom Å unit of length is used, which is equal to \[{10^{ - 10}}\] metres (m).
As it is used to express wavelengths of visible light, ultraviolet (uv light), x-rays and gamma rays.
Wavelength is denoted by \[\lambda \] (lambda)
So, the correct answer is “Option D”.
Note: This is an information question; Angstrom is a unit of length used to measure wavelength of high in the direction of wave. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 405–790 THz.
