reen plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound responsible for light absorption and the color of plants, chlorophyll, strongly absorbs light with a wavelength of 453.nm. Calculate the frequency of this light. Round your answer to 3 significant digits.

The frequency of the light is 6.62 * 10¹⁴ Hz

Explanation:

The frequency of a wave is defined as the number of complete oscillations made by the wave per second. Its unit is Hertz. The frequency of light as well as the velocity of the light and wavelength of the light are all related.

The velocity of light is the distance the light wave travels per second.

Wavelength is defined as the distance between successive crests and troughs of the wave. It is inversely related to the frequency of the wave.

The velocity of light, c is related to frequency, f, and wavelength, λ, by the formula, c = λf

where the velocity of light, c is a constant = 3 * 10⁸ m/s

λ is wavelength of light = 453 nm = 4.53 * 10⁻⁷ m

Frequency, f = ?

Making f subject of formula in the equation above, f = c/λ

f = 3 * 10⁸ m/s / 4.53 * 10⁻⁷ m

f = 6.62 * 10¹⁴ Hz

Therefore, the frequency of the light is 6.62 * 10¹⁴ Hz

your answer is c) plasma
