A: Given in question -    Index of refraction(n) = 1.50 To find -Calculate the angle of incidence that…

Q: What percentage of light is transmitted by two ideal Polaroids, one on lop of the other with their…

A: Assume that the both the Polaroids are vertical. The incoming is not polarized so that it will have…

Q: Calculate the power received by the pupil of eye when the source of the light has intensity of 4.8 ×…

A: Power is defined as the energy per unit time. It is given by, P=IA Here I is the intensity and A is…

Q: Which are more easily diffracted by ordinary objects, AM radio waves or FM radio waves? Explain why

A: AM radio waves.

Q: With an eyepiece field number of 18, what is the size (μm) of an object that covers 1/3 of the Field…

A: Given: Field number of the eyepiece = 18 Solution: The field number of the eyepiece is known as the…

Q: Why are polarizing sunglasses better than glasses that simply reduce the total amount of light?

A: Light waves are made of electric and magnetic fields. These electric waves vibrate in all…

Q: For an spectrometer lecture of 172 degrees- 30’, what would be the diffraction angle? Select the…

A: As we know that: 1 degree equivalent to 60 minutes: So, 30 minutes equivalent to 30/60 degrees which…

Q: How does the polarization of light contribute to the "glare" observed from reflective surfaces?

A: Polarization also occurs when light is scattered while traveling through a medium. When light…

Q: Which of the following is the ratio of the velocity of light in a vacuum and its velocity in a given…

A:

Q: What would you expect the speed of light to be slightly less in atmosphere than in a vacuum?

A: Light is electromagnetic wave. So, they travel at 299,792,458 metres per second (approximately 3 x…
