If white light illuminates a diffraction grating having 710 lines/mmlines/mm , over what range of angles does the visible mm

Complete Question

The human eye can readily detect wavelengths from about 400 nm to 700 nm. If white light illuminates a diffraction grating having 710 lines/mm, over what range of angles does the visible m = 1 spectrum extend

The  value  

Explanation:

From the question we are told that

   The  diffraction grating haves

Generally the separation of the slit is mathematically represented  as

 Generally the condition for constructive interference is mathematically represented as  

So

=>      

=>        

c)as speed changes, wavelength and frequency change.

everything changes!
