Step 1
0 µm = \(22.0 \times 10^{-6}\) m - Distance to the screen (\(L\)) = 2.50 m - Distance from the center to the fifth nodal line (\(y\)) = 37.5 cm = 0.375 m - Order of the nodal line (\(m\)) = 5 Show more…

A student performs Young's double-slit experiment using a slit separation of 21.6 μm. A screen is placed 3.50 m from the centre of the sources such that a point on the fifth nodal line is 37.5 cm from the centre of the interference pattern.

A student performing Young's double slit experiment with a single-colour source finds the distance between the first and the seventh dark spots to be 6.0cm. The screen is located 3.0m from the two slits. The slit separation is 2.2 × 102μm. Calculate the wavelength of the light.
