15 Questions
What is diffraction?
Diffraction is the process by which a beam of light is spread out as it passes through an aperture or across the edge of an object.
What is the condition for diffraction to occur?
The aperture (or hole or slit) has to be comparable to the wavelength of the wave.
What happens when light passes through an aperture and diffracts?
An interference pattern is produced.
What is an interference pattern for light?
An interference pattern for light is a region of light and dark areas created by the overlapping of multiple light waves.
What is constructive interference?
Constructive interference occurs when the peaks of two waves meet, resulting in a bright area.
What is destructive interference?
Destructive interference occurs when the peak of one wave meets the trough of another, resulting in a dark area.
What are the two types of interferences that can result from diffraction?
The two types of interferences that can result from diffraction are constructive interference and destructive interference.
What is diffraction?
Diffraction is the process by which a beam of light is spread out as it passes through an aperture or across the edge of an object. It produces an interference pattern with light and dark areas.
What is an interference pattern?
An interference pattern is a region of light and dark areas created by the overlapping of multiple light waves. It is formed when the peaks or troughs of waves meet, resulting in constructive or destructive interference.
What happens to the diffraction pattern when the aperture becomes smaller?
When the aperture becomes smaller, the diffraction pattern becomes wider and the light and dark bands get dimmer.
What did the author observe in the lab with a single slit aperture?
The author observed a diffraction pattern with a large central maximum and alternating bands of dark and light on each side.
What equipment was used in the lab experiment?
The equipment used in the lab experiment included scissors, razor blade halves, duct tape, slide-frame, clothes pins, and a laser pointer.
How did the author adjust the laser pointer to change the aim?
The author raised or lowered the clothes pins on the cylindrical laser pointer to adjust the aim.
What is the purpose of cutting the razor blade into two halves?
The purpose of cutting the razor blade into two halves is to create a slit with cutting edges pointed towards each other.
What is the maximum width of the slit in the lab experiment?
The maximum width of the slit should be around 1 millimeter.
