Thin Film Interference: Newton’s Rings/Air Wedge with Monochromatic Light

Tempo de Duração: 4:47 minutos

Descrição: To  observe and examine the interference which takes place when light reflects from the surfaces of a thin film. Using two optically flat glass plates to create a thin film of air, interference will be observed when the plates are illuminated with monochromatic light. Newton’s rings will also be observed by replacing one of the flat glass surfaces with a convex surface.

Diffraction and Interference: Microwave Diffraction

Tempo de Duração: 4:46 minutos

Descrição: To  determine if diffraction and interference are observed for electromagnetic waves which fall outside of the visible light range. By using a microwave generator and a transmitting antena, a single-slit microwave diffraction pattern will be produced. In addition, the generation of microwaves from two separate sources will allow microwave interference to be observed.

Diffraction and Interference: Single-Slit Diffraction

Tempo de Duração: 3:19 minutos

Descrição: To  observe and examine the diffraction which occurs when light is incidente on a single narrow slit. The diffraction pattern will be produced by allowing monochromatic laser light to pass through a narrow slit and fall on a screen.

Diffraction and Interference: Double-Slit Interference

Tempo de Duração: 3:42 minutos

Descrição: To  observe and examine the interference/diffraction which occurs when light passes through a double-slit. The interference pattern will be produced by allowing monochromatic laser light to pass through two narrow slits and fall on a screen.
