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!!

Describe how Bohr’s model used the work of Maxwell.
pochemuha

Answer:

 The bohr's model is the primitive model for the hydrogen atom, comparatively to the atom of valence shell. And it is derived from the hydrogen atom of the first approximation by using the quantum mechanics.

Basically, the model state that the electron revolved around in circular orbit in atom around the central nucleus. And it can be fixed in the circular orbit at the set of discrete distance at the nucleus.
