200
The measure from one crest to another or one trough to another is also know as the ________ of a transverse wave.
Wavelength
200
The magnetic field is the strongest where on a magnet?
The ends, poles.
300
When a wire is connected to one end of a power source, ran through a light bulb and then connected to the other end of the power source, the bulb lights. What is being sent through the closed circuit to light the bulb?
Electric current
300
Magnetic field lines leave from which end of the magnet and enter in which end of the magnet?
Leave from the North, enter in the South
300
What are two examples of mechanical waves?
Transverse and Longitudinal
300
When the coils/particles in a longitudinal wave are close together we call this the __________ of a longitudinal wave
Compression
300
What are three consistent properties of all waves?
Amplitude, wavelength and frequency
400
What takes mechanical energy and turns it into electrical energy?
A generator
400
What are the two ways to strengthen an electromagnet?
Increase the # of coils and increase the power of the battery
400
Which type of wave can not only be mechanical, but also electromagnetic?
Transverse
400
the maximum vertical (crest or trough) distance a point on the wave moves from its resting, or equilibrium, position is called the waves ________.
Amplitude
400
How are frequency and wavelength related? (Hint: they are ______________ proportional)
Inversely Proportional
500
When multiple bulbs each have their own circuit they all get the same amount of current without having to split it. This causes all the bulbs to not only light the same but be brighter. What type of circuit is this?
Parallel Circuit
500
When a wire is connected to a power source and wrapped around a core it creates an electromagnet. This electro magnet works because a current is pushed through the wire it creates a ________ _________ around the wire.
Magnetic Field
500
There are 3 examples for mechanical waves. Two of them we learned in detail (longitudinal and transverse). What is the third?
Surface Waves
500
Longitude waves have compressions and __________, which are discerning features of the wave which are only seen on longitudinal and not transverse.
Rarefactions
500
What is the formula for speed of a wave? (Speed = ___ _ ____)
Speed = Frequency x Wavelength
