SUMMARY

The discussion centers on the effects of submerging a Young’s double-slit apparatus in water on the fringe pattern observed. It is established that the fringe pattern becomes less spread out due to the reduction in wavelength of light in a denser medium. The frequency of light remains constant regardless of the medium, confirming that the statement regarding the fringe pattern is true. Key concepts include the relationship between wavelength, frequency, and the medium through which light travels.

PREREQUISITES
  • Understanding of wave properties, specifically wavelength and frequency
  • Familiarity with Young’s double-slit experiment
  • Knowledge of light behavior in different media
  • Basic grasp of the equation c = f(λ)
NEXT STEPS
  • Research the impact of different media on light wavelength and speed
  • Explore advanced concepts in wave optics, including interference patterns
  • Learn about the principles of refraction and its effects on light behavior
  • Study the mathematical derivation of fringe spacing in Young’s double-slit experiment
USEFUL FOR

Students in physics, educators teaching wave optics, and anyone interested in the principles of light behavior in various media.

[SOLVED] question about light

Homework Statement


True or False question
5. If a Young’s double-slit apparatus, having operated in
air, were to be submerged in water, the fringe pattern
would become less spread out.


Homework Equations


c=f(lamda)


The Attempt at a Solution


What i think they mean: does the wavelength become shorter when light is traveling in a slower medium?

What i don't know is does the frequency of light stay constant regardless of the medium?
If yes, then the statement is true.
 
Physics news on Phys.org
Yes, the frequency is constant regardless of medium. The frequency of a wave only depends on the oscillations of the source of the wave.
 
Thank you.
