A ray of light traveling in water hits a glass surface. The index of refraction of the water is 1.33, and that of the glass is 1
kirza4 [7]

Answer:

\mu=41.5\textdegree

Explanation:

From the question we are told that:

Water index of refraction i_w=1.33

Glass index of refraction i_g=1.50

Generally the equation for Brewster's law is mathematically given by

 \theta=tan^{-1}(\frac{i_g}{i_w})

 \theta=tan^{-1}(\frac{1.50}{1.33})

 \theta=48.44 \textdegree

Therefore Angle of incident to plane  \mu (normal at 90 degree to the surface)

 \mu=90\textdegree-\theta

 \mu=90\textdegree-48.44\textdegree

 \mu=41.5\textdegree

Answer:

<h3>U_{2}=4U_{1}</h3><h3>Explanation:</h3>

Let U1 and U2 be the gravitational potential energy of the first and second stone  respectively.

U1 is given by:

U_1 = (m)gh\\

and U2 is given by:

U_2 = (4m)gh  

therefore, comparing the energies we have:

\frac{U_2}{U_1} = \frac{(4m)gh}{(m)gh}= 4

therefore:

U_2=4U_1
