Answer:
Work = 5941 J
Explanation:
As we know that work done is given by the equation
here we know that
also we have
now from above formula we have

It takes 20347.4098071s for light from the sun to reach Pluto.
The 6.1*10^9 is replaced by 6.1*10^12 on line 4 because we convert the distance from km to m.
c = speed of light. If a different value was given in the previous question then use that instead of the value I used to do the final calculation.
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
frequency of light will not change with change in medium but it will depend on the source only
so here frequency of light will remain same in both water and glass and it will be same as that in air
Part b)
As we know that the refractive index of water is given as
so the wavelength in the water medium is given as
Similarly the refractive index of glass is given as
so the wavelength in the glass medium is given as
Part c)
Speed of the wave in water is given as
Speed of the wave in glass is given as
