Alaser beam is incident at an angle of 33.0° to the vertical onto a solution of cornsyrup in water.(a) if the beam is refracted to 24.84° to the vertical, what is the index ofrefraction of the syrup solution? (b) suppose the light is red, with wavelength 632.8 nm in a vacuum. find its wavelength in the solution.(c) what is its frequencyin the solution? (d) what is its speed in the solution?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.
