Questions
- The speed of light in crown glass is #1.67*10^8#. What the index of refraction?
- 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?
- SNELLS LAW: light travels from water into fibre optic cable with an angle of refraction of 21.5° what is the angle of incidence?
- How does a refractive index of water compare with that of glass?explain
- Light travels at approximately #3.0*10^8# #m##/##sec#, How far does light travel in one week?
- 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?
