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 . Calculate the frequency of this light.

This question is incomplete

Explanation:

This question is incomplete because of the absence/omission of the wavelength but the completed question is attached below.

The formula for frequency is f = c/λ

where f is the frequency (unknown)

c is the speed of light (3.0 × 10⁸ m/s)

λ is the wavelength (599 nm)

f = (3 × 10⁸) ÷ 599

f = 500834.73 Hz or 5 × 10⁵ Hz

Jenny and fred both play a long note on their trombones. a stationary observer hears the sound increasing and decreasing repeatedly in loudness. which of these must be true? the sound waves from the two trombones have slightly different frequencies.the sound waves from the two trombones have the same frequency.the sound waves from the two trombones have slightly different amplitudes.the sound waves from the two trombones have the same wavelength.the sound waves from the two trombones have slightly different velocities.  lolthe answer is          the sound waves from the two trombones have slightly different frequencies.
