7.76 The sun emits many wavelengths of light. The brightest
light is emitted at about 0.48 um. What frequency does this
correspond to?

Respuesta :

The corresponding frequency  is [tex]6.25 \times 10^{14} \mathrm{Hertz}[/tex]

Step-by-step explanation:

Given:

The brightest light is emitted =0.48 μm

To find:

Frequency= ?

Solution:

We know ,

[tex]1 \mu m=10^{-6} \text { meters }[/tex]

Hence,

[tex]0.48 \mu m=0.48 \times 10^{-6} \mathrm{meters}[/tex]

Now,

[tex]\text {frequency }=\frac{\text {speed of lightc}}{\text {wavelength}}[/tex]

Substituting the known values

[tex]\text { frequency }=\frac{\left(3.00 \times 10^{8} \text { meters per second }\right)}{\left(0.48 \times 10^{-6} \mathrm{meters}\right)}[/tex]

[tex]\text {frequency }=6.25 \times 10^{14} \mathrm{Hertz}[/tex]

Thus the frequency is [tex]6.25 \times 10^{14} \mathrm{Hertz}[/tex]
