Answer:
Frequency is inversely proportional to wavelength.
Explanation:
frequency is the number of oscillations in a unit of time.
Wavelength is the length between one oscillation and the next oscillation.
take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)
Now get two pins and pin them at a certain distance apart.
take the first spring and attach its two terminals to the pins.
Repeat the above procedure, but double (increase the distance x2) the distance between two pins.
Now you have to measure how many coils are there within 5cm of the two springs.
you'll observe that the second spring has half the coils of the first spring within 5cm.
In here no. of coils is the frequency
5cm length is time.
distance between coil is the wavelength.
Two functions of the skeleton system are:
- It is a support structure for the body
- It provides protection our internal organs
