Which action would have the least effect on the strength of an electromagnet?
changing the amount of current
changing the currents direction
changing the number of wire loops or coils
changing the size of the metal core
What device changes mechanical energy in to electric energy?
battery
electric motor

A switch opens and closes a circuit. What does it mean if a switch is closed?
the circuit is on
the circuit is off
the electricity will not flow
the circuit is not complete.
What is this device and what does it do to the electricity?
it is a step up transformer therefore decreases electric voltage
it is a step down transformer therefore increases electric voltage
it is a step up transformer therefore increases electric voltage
it is a step down transformer therefore decreases electric voltage.
The following diagram show what type of wave?
transverse wave
longitudinal wave
compressional wave
rarefactional wave
What is the property shown in position C?
amplitude
wavelength
frequency
trough
What is the number of waves that pass a point in 1 second called?
amplitude
frequency
intensity
wavelength
When comparing the types of electromagnetic waves, which has the greatest energy?
ultraviolet
x-rays
gamma rays
visible light
If these waves were sound waves which would have the lowest pitch?
A
B
C
If the following waves were light waves which one would most likely be violet in color?
A
B
C
The color of light is determined by the
frequency of the wave
amplitude of the wave
pitch of the wave
wavelength of the wave
Ultraviolet rays are dangerous electromagnetic waves from
the sun
nuclear fission
electrons
x-rays
Sound waves
are electromagnetic waves therefore can travel trough space
are mechanical waves therefore cannot travel trough space
are transverse waves that travel faster than light
are like light waves and can travel without a medium
Which statement best explains what there could be a force of attraction between two electrically charged objects?
because they are like charges
because they are unlike charges
because they have the same number of protons
because they have the same number of electrons
A
B
C
D
What wave property is shown by position D?
amplitude
wavelength
frequency
trough
