In the virtual lab, calculations were made of the predicted diffraction angle, using the formula

θ ≈ StartFraction lambda over L EndFraction.

where θ is the diffraction angle in radians, λ is the wavelength, and L is the width of the gap in the barrier. Radians were then converted to obtain the diffraction angles in degrees. Now verify your calculations.

The predicted angle of diffraction with a 3 cm wavelength was degrees.

The predicted angle of diffraction with a 4 cm wavelength was degrees.

The predicted angle of diffraction with a 5 cm wavelength was degrees.
