When light passes from a more-dense to a less-dense medium—from glass to air, for example—the angle of refraction predicted by snell's law can be 90° or larger. in this case the light beam is actually reflected back into the denser medium. this phenomenon, called total internal reflection, is the principle behind fiber optics. snell's law is given below. sin(θ1) sin(θ2) = v1 v2 set θ2 = 90° in snell's law and solve for θ1 to determine the critical angle of incidence at which total internal reflection begins to occur when light passes from diamond to air. (note that the index of refraction from diamond to air is the reciprocal of the index from air to diamond. round your answer to one decimal place.)

Explanation:

= Refractive index of air = 1

= Refractive index of diamond = 2.41

= Angle in air

= Angle in diamond = 90° (TIR)

From Snell's law we have

The angle will be

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
