Question | Answer |
Wave | Vibrations in a medium |
Medium | the material through which a wave can travel |
Transverse wave | a wave which the object moves up and down as the wave passes |
Crest | the points where the wave is the highest |
Trough | the points where the wave is the lowest |
Longitudinal wave | a wave which the particles move back and forth in the same direction the waves travel |
Compression | when you compress the wave closer toghether |
Rarefaction | when you spread the wave apart |
Mechanical waves | waves that require a medium |
Electromagnetic waves | waves that can travel without a medium |
Amplitude | the measure of how far particles in the medium move from their rest position |
Wave length | the distance over which the shapes repeat |
Frequency | the number of waves that pass a point in a given amount of time |
Hertz | What frequency is measured in |
Wave speed | the speed that waves travel |
What is the equation for wave speed? | wave speed=wave length divided by wave period |
Force | a push or pull exerted on an object in order to change the motion of an object newtons |
Work | the use of force to move an object some distance |
What is the unit of measurement for work? | Joules |
What is the equation for work? | Work=force times distance |
Power | a strong force |
A 900N mountain climber scales a 100m cliff. How much work is done by the mountain climber? | 90,000 J |
Angela uses a force of 25N to lift her grocery bag while doing 50 J of work. How far did she lift the grocery bags? | 2m |
A machine does 40 J of work in 10 seconds. How much power is that? | 4 watts |
What is power measured in? | Watts |
A machine does 30 J of work in 10 seconds. How much power is that? | 3 watts |
Give an example of a medium. | Slinky, sound particles |
Mariah hears the orchestra play in a concert. What kind of wave would the sound travel through? | Longitudinal wave |
What kind of wave would your heart rate show? | Transverse wave |
What would be the medium in a sound wave? | Sound particles |
A wave with a frequency of 60 Hz travels through steel with a wavelength of 85.5 m. What is the speed of this wave? | 510 m/s |
