The wavelength of a photon is 622nm and it is a red light.
<h3>What is Wavelength?</h3>
The length of a waveform signal that is propagating in space or over a wire is measured by the separation between identical points (adjacent crests) in the adjacent cycles. This length is typically specified in meters (m), centimetres (cm), or millimetres (mm) in wireless systems (mm).
<h3>What is Photon?</h3>
A discrete bundle (or quantum) of electromagnetic (or light) energy is referred to as a photon. Photons move at the speed of light (3 108 m/s) because they have no mass.
<h3>What are the calculations?</h3>
λ = v/f
where, f = frequency = 4.82 ×
v = speed of light = 3 × m/s
λ = 3 × / 4.82 ×
λ = 6.22 ×
λ = 622 nm.
Hence, the wavelength of a photon is 622nm and it is red light.

B, because elements only bond to form a full valence electron shell (8 electrons). They do this so that they can become stable.
Pastoral farming is best described as a method of raising livestock and moving herds.
<h3>What is pastoral farming</h3>
Pastoral farming is a system of farming that aims at producing animals rather than crops.
In pastoral farming, the herd of animals are moved from one place to another in search of food and water.
Therefore, pastoral farming is best described as a method of raising livestock and moving herds.
