Q: Total internal reflection is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, the wave cannot pass through and is entirely reflected. The critical angle is the angle of incidence above which the total internal reflection occurs. This is particularly common as an optical phenomenon, where light waves are involved, but it occurs with many types of waves, such as electromagnetic waves in general or sound waves. When a wave reaches a boundary between different materials with different refractive indices, the wave will in general be partially refracted at the boundary surface, and partially reflected. However, if the angle of incidence is greater (i.e. the direction of propagation is closer to being parallel to the boundary) than the critical angle -- the angle of incidence at which light is refracted such that it travels along the boundary -- then the wave will not cross the boundary, but will instead be totally reflected back internally. This can only occur when the wave in a medium with a higher refractive index (n) reaches a boundary with a medium of lower refractive index (n). For example, it will occur with light reaching air from glass, but not when reaching glass from air.
Can we conclude that does total internal reflection occur at the critical angle?

Q: Rake is an Australian television program, produced by Essential Media and Entertainment, that first aired on the Australian Broadcasting Corporation's ABC1 in 2010. The fourth series started on ABC TV on 19 May 2016. It stars Richard Roxburgh as rake Cleaver Greene, a brilliant but self-destructive Sydney barrister, defending a usually guilty client. The show airs in the United States on DirecTV's Audience Network and is available on Netflix in the UK, Ireland, Canada, the United States, the Netherlands, India, Australia and New Zealand. A fifth and final series went into production in October 2017 and premiered on August 19, 2018.
Can we conclude that is there going to be a new season of rake?
