This question really has me stumped..i would appreciate it if anyone could help me out
White light containing wavelengths of 400nm to 750 nm is shone normally onto a diffraction grating of 3000 lines/cm. Calculate the width of the spectrum that appears as the second antinode on a screen that is 100 cm away.
Is there a specific formula I can use to solve the question? If so then please help.. thanks
