Question

What is the wavelength (in nm) of light with a frequency of- ^^ see picture

Answer 1

i think this is the answer 750 nm - 400 nm

Answer 2

Frequency =6.75×10^14s^{-1}

`\\ \sf\longmapsto \lambda=(c)/(v)`

`\\ \sf\longmapsto \lambda=(3* 10^8m/s)/(6.75* 10^(14)s^(-1))`

`\\ \sf\longmapsto \lambda=0.444* 10^(-6)m`

`\\ \sf\longmapsto \lambda=0.4\mu m`
