The critical angle for total internal reflection at a liquid-air interface is 41.0. (1) if a ray of light traveling in the liquid has an angle of incidence of 34.5 at the interface with respect to the normal, what angle does the refracted ray in the air make with the normal? (2) if a ray of light traveling in air has an angle of incidence of 34.5 at the interface with respect to the normal, what angle does the refracted ray in the liquid make with the normal?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
