282246 The phenomenon involved in the reflection of radio-waves by ionosphere is similar to :

1 reflection of light by plane mirror
2 total internal reflection of light in air during a mirage
3 dispersion of light by water molecules during the formation
4 scattering of light by air particles

282247 Glass has refractive index ' \(\mu\) ' with respect to air and the critical angle for a ray of light going from glass to air is ' \(\theta\) '. If a ray of light is incident from air on the glass with angle of incidence ' \(\theta\) ', corresponding angle of refraction is

1 \(\sin ^{-1}\left(\frac{1}{\sqrt{\mu}}\right)\)
2 \(\sin ^{-1}(\sqrt{\mu})\)
3 \(\sin ^{-1}\left(\frac{1}{\mu^2}\right)\)
4 \(\sin ^{-1}\left(\frac{1}{\mu}\right)\)

282268 Secondary rainbow in the atmosphere is

1 the result of polarization and dispersion of light
2 brighter than the primary rainbow
3 due to the phenomenon of double refraction
4 formed with red colour on the top
(e) formed due to two reflections in the rain drop

282248 An object is fixed at the bottom of a vessel and water is filled in the vessel upto a height of \(10 \mathrm{~cm}\). A plane mirror is placed at a height of 7 \(\mathrm{cm}\) from the surface of water in such a way that its reflecting surface faces the water. The distance of the image from the mirror is (Refractive index of water, \(n=1.33\) )
