Which of the following types of waves is not part of the electromagnetic spectrum?
All electromagnetic waves have the same frequency.
Which one of the following statements concerning electromagnetic waves is false?
Which one of the following expressions gives the correct relationship between the magnitudes of the electric and magnetic fields of an electromagnetic wave?
the direction the wave is traveling and the direction in which energy is transported
What does the Poynting vector at a given point describe?
Electromagnetic waves can exert pressure on an object.
Electromagnetic waves have linear momentum as well as energy. What does this imply about electromagnetic waves?
All of the electromagnetic waves directed toward an object are reflected by it.
In which one of the following cases does the radiation pressure have the largest value?
the direction of the electric field component.
Complete the following statement: The polarization direction of an electromagnetic wave is determined by
When unpolarized light is incident on a sheet of polarizing material with a transmission axis oriented vertically, what percentage of the light is transmitted through the material?
one hundred percent
When vertically polarized light is incident on a sheet of polarizing material with a transmission axis oriented vertically, what percentage of the light is transmitted through the material?
When horizontally polarized light is incident on a sheet of polarizing material with a transmission axis oriented vertically, what percentage of the light is transmitted through the material?
What is the name for the principle or law that allows one to determine the average intensity of polarized light that will be transmitted through a sheet of polarizing material?
Light travels through the boundary of two different materials.
Which one of the following sentences best describes the term refraction?
What is the angle of refraction when the angle of incidence is equal to the critical angle?
Light is traveling in a material that has a smaller index of refraction than material surrounding it.
In which one of the following cases will total internal reflection occur?
tan ϴb = n2/n1
Which one of the following expressions is Brewster's law?
The electric field amplitude of wave A is one half that of wave B.
The intensity of electromagnetic wave A is one fourth that of wave B. How does the magnitude of the electric field of wave A compare to that of wave B?
Unpolarized light with intensity Sis incident on a series of polarizing sheets. The first sheet has its transmission axis oriented at 0°. A second polarizer has its transmission axis oriented at 45°and a third polarizer oriented with its axis at 90°. Determine the fraction of light intensity exiting the third sheet with and without the second sheet present
Horizontally polarized light of intensity Sis incident on a polarizer with its transmission axis oriented at 45°. Determine the fraction of light intensity exiting the polarizer.
Unpolarized light of intensity Sis directed toward three polarizing sheets. The first sheet is polarized vertically; and the last sheet is oriented horizontally. If the middle sheet is also oriented vertically, what is the intensity of the light exiting the last polarizer?
This is not possible since no angle θ will satisfy this situation.
A laser beam is directed at the left side of a plastic block (n= 1.53) as shown at an angle θ . The beam then undergoes total internal reflection as the light strikes the top interface at the critical angle for the block and the surrounding air. What is the value of the angle θ ? Note: The drawing is not drawn to scale and the angles shown are not the actual angles.
