Humans have three types of cone cells in their eyes, which are responsible for color vision. Each type absorbs a certain part of the visible spectrum. Suppose a particular cone cell absorbs light with a wavelength of 549.nm. Calculate the frequency of this light. Be sure your answer has the correct number of significant digits.

5.46 x 10¹⁴ Hz

Explanation:

The relation between frecuency (ν) and wavelength (λ) is given by:

c = λν

Where c is the speed of light and it is constant: 2.998 x 10⁸ m/s.

Given: λ = 549 nm x 10⁻⁹ m/1 nm = 5.49 x 10⁻⁷ m

We calculate the frequency of the light as follows:

ν = c/λ = (2.998 x 10⁸ m/s)/(5.49 x 10⁻⁷ m) = 5.46 x 10¹⁴ s⁻¹ = 5.46 x 10¹⁴ Hz

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
