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.

The velocity of car is 80.0 miles per hour. what is the velocity of car in meters per second? (1 km -0.621 miles) m/s

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
