A student shines a red laser at two slits in a piece of paper. The slits are 0.080 mm apart. A screen is placed 2.0 m away from the slits. Upon taking measurements, the student determines that there are 5.0 cm between the first and fourth nodal lines. the distance from the centre of the pattern to the third nodal line is 4.2 cm. the angle to the eighth anti-nodal line from the right bisector is 3.8°.
Perform three different calculations to determine the wavelength of this light. Account for any difference in values.
