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

Answer:

Explanation:

Given

angular frequency ranging From $2.7\times 10^{15}\ rad/s\ to\ 4.7\times 10^{15}\ rad/s$

we know $\omega =2\pi f$

where $f=frequency$

$\omega =angular\ Frequency$

for $\omega =2.7\times 10^{15}$

$f=\frac{2.7\times 10^{15}}{2\pi }$

$f=4.29\times 10^{14} Hz$

for $\omega =4.7\times 10^{15}$

$f=\frac{4.7\times 10^{15}}{2\pi }$

$f=7.47\times 10^{14} Hz$

Frequency ranges from  $4.29\times 10^{14}\ Hz\ to\ 7.47\times 10^{14} Hz$
