301
Air has refractive index 1.0003. The thickness of air column which will have one more wavelength of yellow light (6000 Å) than in the same thickness of vacuum is
302
108. When a ray is refracted from one medium into another medium, the wavelength changes from 6000 Å to 4000 Å. The critical angle for a ray from the second medium will be
303
Monochromatic light passing through a thick prism is
304
Which one of the following lights travels fastest in optical fibers?
305
The blurring of the image due to dispersion in lenses is called
306
Light of wavelengths 4000 Å and 5000 Å falls from air on a quartz surface at an angle of incidence 30°. The indices of refraction for the two wavelengths are 1.47 and 1.48 respectively. The angle between the two refracted rays is:
307
A beam of monochromatic light is refracted from vacuum into a medium of refractive index 1.5. The wavelength of refracted light will be
308
When light of wavelength λ is incident on an equilateral prism kept at its position of minimum deviation, it is found that the angle of deviation equals the angle of the prism itself. The refractive index of the material of the prism for the wavelength λ is:
309
A ray of light consisting of two wavelengths 4000 Å and 5000 Å falls from air on a quartz surface. The angle of incidence is 30°, and the indices of refraction for the two wavelengths are respectively 1.47 and 1.46. The angle between the two refracted beams will be
310
When an obliquely falling ray of light enters from one medium to another, it changes its path. This phenomenon is called
