The velocities of light in two different media are 2*`10^8`m/s and 2.5 * `10^8`m/s respectively.The critical angle for these media is sin^(-1)((1)/(5)) sin^(-1)((4)/(5))

The velocities of light in two different media are 2xx10^(8) m/s and 2.5xx10^(8) m/s respectively. The critical angle for these media is

The velocities of light in two different mediums are 2xx10^(8) ms^( -1) and 2.5xx10^(8) ms^(-1) respectively. The critical angle for there mediums is

The velocities of light in ice and diamond are 2.3 xx 10^(8)m//s and 1.25 xx 10^(8) m//s respectively. The R.I. of diamond with respect to ice is

Light ray is travelling from a denser medium into a rarer medium. The velocity of light in the denser and rarer medium is 2 xx 10^(8) m/sec and 2.5 xx 10^(8) m / sec. The critical angle of the two media is

Light travels in two media A and B with speeds 1.8*10^8 m/s and 2.4*10^8 m/s respectively . calculate the critical angle between them.
