Complete Question:
A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness Land index of refraction n=1.5. The wavelength of the laser light in vacuum is L/10 and its frequency is f. In this problem, neither the constant c nor its numerical value should appear in any of your answers.
How long does it take for a short pulse of light to travel from one end of the glass to the other?
Express your answer in terms of the frequency, f. Use the numeric value given for n in the introduction.
Answer:
15/f
Explanation:
Wavelength of the laser light, λ = L/10
Where L = Distance covered by the light
Refractive index, n = 1.5
Speed, v = λf
Since we are considering the laser light, the speed of light, c, will be used.
c = v
c = λf
c = (L/10)f
(L/10)f = L/t
f/10 = 1/t
t = 10/f
since the refractive index, n = 1.5
t = 1.5(10/f)
t = 15/f
Answer:
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is
Explanation:
The relation between the translational rms speed and the temperature is given by :
So,
When the temperature is three times greater.
The ratio of the translational rms speed in the ionosphere to the translational rms near the earth's surface is :
Hence, this is the required solution.
Answer:
The vertical component of the velocity is about 16 m/s.
Explanation:
The vertical component is the magnitude of the velocity reduced by the sinus of the angle 53 degrees. So
Answer:
no because its a elctromagnetic wave
