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
Answer:
The value

Step-by-step 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
![\theta = sin ^(-1) [(n * \lambda )/(d) ]](https://img.qammunity.org/2021/formulas/physics/college/70u90cpyjx2w3b23cm6ciutaz83y1p02go.png)
=>
![\theta = sin^(-1)[(1 * 400 *10^(-9))/( 1.408*10^(-6)) ]](https://img.qammunity.org/2021/formulas/physics/college/8r0gpob6186pti1fn1xdyvexa1r76gsgh0.png)
