This diagram below shows two apertures through which planar waves are passed as they are moving to the left. The wavefronts show crests moving in phase. Given this information, at which point will the amplitude of the waves be a minimum?
When a light ray enters a denser medium and refracts, some of the characteristics of the wave will change. Which of the following options is correct about this change?
Young’s double-slit experiment is setup as shown, including a monochromatic source, a single slit, a double slit and a screen. What is the purpose of the double slit in this experiment?
To make sure there is equal intensity in the double-slits
To make sure the light is coherent upon the double-slits
Identical waves that begin propagation at the same time leave from two different sources and arrive at the same point – point X. The first source is 18 m from point X. The second source is 10.5 m from point X. The waves of both sources have a wavelength of 3 m. What is observed at X?
