Question

Given light with frequencies of: 5.5 x 1014 Hz, 7 x 1014 Hz and 8 x 1014 Hz, calculate the wavelengths in free space. What color are these waves?

Answer 1

Step-by-step explanation:

Given light with frequencies of 5.5 x 10¹⁴ Hz, 7 x 10¹⁴ Hz and 8 x 10¹⁴ Hz

we now,
`\lambda = (c)/(\\u)`

now

1)
`\lambda_1 =(3* 10^8)/(5.5* 10^(14))`

= 545.45 nm

2)
`\lambda_2 = (3* 10^8)/(7* 10^(14))`

= 428.57 nm

3)
`\lambda_3 = (3* 10^8)/(8* 10^(14))`

= 375 nm

the color related to wavelength are

545.45 nm - green

428.57 nm - blue

375 nm - violet
