Suppose a scientist detects an electromagnetic wave with a frequency higher than those of gamma rays. The scientist labels this wave a Z-ray. Which of the following would always be true of a Z-ray?
A Z-ray would have a lesser amplitude than gamma rays.
A Z-ray would have a greater amplitude than gamma rays.
A Z-ray would have a shorter wavelength than gamma rays.
A Z-ray would have a longer wavelength than gamma rays.
Which of the lists below orders the following electromagnetic waves from longest to shortest wavelength?
x-ray, ultraviolet, visible light
ultraviolet, x-ray, visible light
visible light, ultraviolet, x-ray
ultraviolet, visible light, x-ray
Which part of the EM spectrum is used in night vision goggles?
X-ray
Microwave
Visible
Infrared
Which of the following is arranged from highest to lowest frequency?
X-ray, infra-red, red light, UV, radiowave
Radiowave, infra-red, red light, UV, x-ray
Radiowave, UV, red light, infra-red, x-ray
X-ray, UV, red light, infra-red, radiowave
White light is refracted as it passes from the air into a glass prism, separating the colors that make up the original white light. This happens because
all light travels at the same slower speed in glass than in air
all light travels at the same faster speed in glass than in air
different colors of light travel at different speeds in glass
red light travels faster in glass than in air
Light passes from medium 1 into medium 2 and bends along the path shown to the right. Which of the following statements is correct?
Medium 1 is denser than medium 2.
Medium 2 is denser than medium 1.
The speed of the light is greater in medium 2 than in medium 1.
The frequency of light is greater in medium 1.
The diagram on the left represents which of the following forms of wave interaction?
diffraction of light
polarization of light
reflection of light
refraction of light
Which of the following terms best describes the workings of a fiber optic cable?
complete diffraction
the Doppler Effect
total internal reflection
minimal refraction
The location of an image is shown. Considering refraction through a thin convex lens, where is the original object located in order to achieve this image?
Location A
Location B
Location C
Location D
Which statement regarding the following lenses is accurate?
Convex lenses converge light while Concave lenses diverge light
Convex lenses diverge light while Concave lenses converge light
Both lenses diverge light
Both lenses converge light
As you look into a flat mirror, where is your image going to form? Refer to the diagram on the left.
Point A
Point B
Point C
Point D
Consider four charges, A, B, C, D, which exist in a region of space. Charge A attracts B, but B repels C. Charge C repels D, and D is positively charged. What is the sign of charge A?
Positive
Negative
Neutral
All of the charges are positive
If an object is electrically neutral, we can say that it:
Attracts only negative charges
Repels both positive and negative charges
Contains equal numbers of positive and negative charges
Contains no electrons
All transfer of charge is due to the movement of
Neutrons
Electrons
Atoms
Protons
What is the difference between a conductor and an insulator?
An insulator allows electricity to flow through it easily and a conductor does not
A conductor allows electricity to flow through it easily and an insulator does not.
An insulator is magnetic and a conductor is not
A conductor is magnetic and an insulator is not
You’re given 5 different materials to test for conductivity in a circuit. Which of the following is going to happen?
Copper, iron and brass will light up because of high mobility electrons and high conductivity
Copper, glass and brass will NOT light up due to high mobility protons and low conductivity
Wood, iron and glass will light up because of high mobility electrons and high conductivity
Glass and wood will NOT light up due to high mobility protons and low conductivity
