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?

Explanation:

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

we now,

now

1)  

                      = 545.45 nm

2)  

                      = 428.57 nm

3)  

                      =  375 nm

the color related to wavelength are

545.45 nm - green

428.57 nm - blue

375 nm - violet

wavelength variability is the right one

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
