Diffraction of Light starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Diffraction of Light.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A diffraction grating has 5000 lines per cm. What is the grating spacing (d) in meters?
A diffraction grating is used to separate white light into its component colors. Explain why this occurs.
A laser beam of wavelength 650 nm passes through a slit of width 0.1 mm. Calculate the angular width of the central maximum.
A monochromatic light of wavelength 500 nm is incident on a diffraction grating with 6000 lines/cm. Calculate the angle of the first-order maximum.
A monochromatic light of wavelength 600 nm passes through a slit of width 0.2 mm. Calculate the angle for the first minimum.
A slit of width 0.5 mm is illuminated by light of wavelength 400 nm. How many minima will be observed on one side of the central maximum?
Calculate the minimum resolvable angle (θ) for a circular aperture of diameter 2 cm using light of wavelength 500 nm.
Describe the difference between Fresnel and Fraunhofer diffraction.
Describe the effect of using monochromatic versus white light in a single-slit diffraction experiment.
Explain why diffraction is not easily observed with everyday objects and visible light.
Explain why radio waves can bend around buildings while visible light cannot.
Explain why the central maximum in a single-slit diffraction pattern is brighter and wider than the other maxima.
If the width of a single slit is halved, what happens to the width of the central maximum in the diffraction pattern?
In a single-slit diffraction experiment, if the wavelength of light is increased, what happens to the width of the central maximum?
Name the scientist who first observed and explained the phenomenon of light diffraction.
State the condition for the first minimum in a single-slit diffraction pattern.
