A Metallic Sheet Has a Large Number of Parallel Slits $5.0 \mathrm {~mm}$

question 92

Multiple Choice

A metallic sheet has a large number of parallel slits, $5.0 \mathrm {~mm}$ wide and $20 \mathrm {~cm}$ apart. This sheet is used as a diffraction grating for microwaves. A wide parallel beam of microwaves is incident normally on the sheet. If the intensity maxima occur $2.0 ^ { \circ }$ apart in the central region, what is the wavelength of the microwaves?

• A) \(8.0 \mathrm {~mm}\)
• B) \(9.0 \mathrm {~mm}\)
• C) \(7.0 \mathrm {~mm}\)
• D) \(5.0 \mathrm {~mm}\)
• E) \(6.0 \mathrm {~mm}\)
