Problem 3. A pair of narrow parallel slits separated by a distance of 0.274 mm are illuminated by the green component from a mercury vapor lamp (wavelength=545.5nm).(adsbygoogle = window.adsbygoogle || []).push({});

What is the angle from the central maximum to the first bright fringe on wither side of the central maximum? Answer in degrees.

Note: If the formula is: d(sin thetha)=m(wavelength)

What do i do next??

Problem 25.

A diffraction grating is calibrated by using the 546.1 m line of mercury vapor. The first-order maximum is found at an angle of 26.09 degrees. Calculate the number of lines per centimeter on this grating. Answer in units of lines/cm.

Note: How do I start?
