A beam of light traveling through a liquid (of index of refraction n1 = 1.47) is incident on a surface at an angle of θ1 = 49° w
dsp73

Answer:

a) n2=(n1sin1)(sin2)

b) 1.18

c) 201081632.7m/s

d) 254237288.1m/s

Explanation:

a) We can calculate the index of refraction of the second material by using the Snell's law:

n_1sin\theta_1=n_2sin\theta_2

n_2=\frac{n_1sin\theta_1}{sin\theta_2}

b) By replacing in the equation of a) we obtain:

n_2=\frac{(1,47)sin49\°}{sin69.5\°}=1.18

c) light velocity in the medium is given by:

v=\frac{c}{n_1}=\frac{3*10^{8}m/s}{1.47}=204081632.7\frac{m}{s}

d)

v=\frac{c}{n_2}=\frac{3*10^{8}m/s}{1.18}=254237288.1\frac{m}{s}

hope this helps!!
