Question

Vision. When light having vibrations with angular frequency ranging from 2.7×1015rad/s to 4.7×1015rad/s strikes the retina of the eye, it stimulates the receptor cells there and is perceived as visible light.

What are the limits of the frequency of this light?

Answer 1

Step-by-step explanation:

Given

angular frequency ranging From
`2.7* 10^(15)\ rad/s\ to\ 4.7* 10^(15)\ rad/s`

we know
`\omega =2\pi f`

where
`f=frequency`

`\omega =angular\ Frequency`

for
`\omega =2.7* 10^(15)`

`f=(2.7* 10^(15))/(2\pi )`

`f=4.29* 10^(14) Hz`

for
`\omega =4.7* 10^(15)`

`f=(4.7* 10^(15))/(2\pi )`

`f=7.47* 10^(14) Hz`

Frequency ranges from
`4.29* 10^(14)\ Hz\ to\ 7.47* 10^(14) Hz`
