Rad physics

disturbance

A wave is a _____ in any medium which transports ____ from one place to another without causing any permanent change in the medium itself.

transverse

For a _____ type of wave, the displacement of the medium is perpendicular to the direction the wave is traveling.

horizontal or compressional

For a _____ wave, the displacement of the medium is parallel to the direction the wave is traveling

1. aplitude

2. wavelength

3. frequency

4. speed

four characteristic of every wave:

amplitude

The _____ of any wave is the maximum displacement of the medium from its equilibrium position

“strong”

The amplitude is associated with how ____ a wave is

wavelength

The ____ of any wave is defined as the distance between two like points

Cycle

One completion of a wave from before it repeats itself is called a _____

pulses

Each cycle consist of two ______, one positive and one negative

frequency

The _____ of a series of waves is defined as the number of cycles that pass by a given point each second

hertz

The physics unit for frequency is the ____, abbreviated Hz and defined as one cycle per second

v= f^

wave formula solving for velocity

directly proportional

covering up the 8 in the wave formula with your fingertip, we can see that velocity and frequency are _____ _______ to each other

directly proportional

Covering up the f in the wave formula with your fingertips, we see in order to maintain the same frequency in a series of waves, velocity and wavelength would have to be _____ ______.

inversely proportional

covering up the V in the wave formula with your fingertip, we see in order to maintain the same frequency and wavelength will be _____ ______ to each other.

Draw and fill in the “T” triangle here for wave formula

frequency and wavelength

To find the speed of a series of waves, multiply:

speed by wavelength

To find the frequency of a serie sof waves, divide:

speed by frequency

To find the wavelength of a series of waves, divide:
