Answer:
5.5 × 10^14 Hz
Explanation:
The wavelength can be represented using the formula;
λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3 × 10^8m/s)
f = frequency (Hz)
According to this question, a light associated with the visible spectrum has a wavelength of 550 nm.
550nm = 550 × 10^-9m
f = v/λ
f = 3 × 10^8 ÷ 550 × 10^-9
f = 0.0055 × 10^ (8+9)
f = 0.0055 × 10^17
f = 5.5 × 10^14 Hz
The frequency is 5.5 × 10^14 Hz
Answer: The most commonly cited impact is deforestation, i.e., the clearance of forest or woodland. At a small spatial scale this may indeed be the case but on a larger landscape scale charcoal production most frequently results only in forest degradation. The contribution of charcoal to deforestation in the tropics is less than 7%. Charcoal production most frequently results in forest degradation. Most charcoal areas have the potential for rapid forest recovery.
