  • How quickly does light travel?
  • Light with wavelength #lambda# and frequency #f# in air slows to a speed #v# when transmitted through a piece of plastic. What is the light's frequency in the plastic? What is the light's wavelength in the plastic?
  • See breeze and land breeze occurs at night. Why?
  • The work of which scientist(s) helped to explain light's ability to propagate through a vacuum?
  • Is it possible for a material to have a refractive index less than #1.000#?
  • Does light use any route to travel like we drive a car on road?
  • What value would u give the actual index of refraction of the plastic block?
  • What determines the speed of light in a medium?

  • Light travels at approximately #3.0*10^8# #m##/##sec#, How far does light travel in one week?
  • A monochromatic beam of light passes obliquely from flint glass into air. How do the characteristics of beam of light changes?
  • Light speed in a medium is measured as 2×108 m/s. What if the index of refraction for the medium? What is the apparent depth of a fish with real depth of 9 meters in the medium?
  • Suppose a small plane can fly at 300 km/h [N] relative to the surrounding air. Suppose also that there is a 60 km/h [N] tailwind. How fast does the plane's shadow move across the ground?
  • Submarine 300m from the shore and 100m beneath sea surface. A laser light from the sub strikes the water surface at 210m from the shore. If the light just strikes top of a cliff at the water's edge, what is the cliff height?
  • A possible means for making an airplane invisible to radar is to coat the plane with an antireflective polymer. If radar waves have a wavelength of 3cm and index,n polymer=1.5, how thick would you make the coating?
  • The index of refraction for water is 1.33 and for glass it is 1.52. What happens to the speed of light when light travels from water into glass?
