Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA.
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
