Question
1. A screen is located 1.7 m from a single slit of width 3.5 µm. If light from a helium-neon laser of wavelength 593.9 nm shines on the slit, determine the position of the first minimum on the screen. (Enter the magnitude.) __________m
2. The two slits of a double-slit apparatus each have a width of 0.121 mm and their centers are separated by 0.847 mm. What orders are missing in the diffraction pattern? (Give your answer in terms of m.) n= ___________m
3. A narrow slit is illuminated with light of wavelength 700.0 nm, 1.7 m in front of a screen. The first minima on either side of the central maximum of the diffraction pattern observed are separated by 3.1 mm. Determine the width of the slit. ____________m
Explanation / Answer
ACCORDING TO THE CHEGG GUIDELINES I AM ALLOWED TO ANSWER ONLY (FIRST ) ONE QUESTION AT A TIME.
1) Here we need to find the value of the position of the first minimum on the screen
y = mD/w
y = 1.00 * 593.9 * 10 ^ -9 m * 1.700 m / 3.50 * 10 ^ -6
y = 0.288465714 m =====================================ANSWER)
