About me

Hi! I'm Sarah and I'm a second year Physics student at the University of Exeter.  Maths and Physics have been a huge part of my education and general interests for a long time and I hope that I can pass on my knowledge and enthusiam to you! I know that these can be intense, difficult subjects, which is why I'll be very patient and reassuring with any problems you may have.  I can also help with GCSE Economics, which I took for A Level, with confidence as it was a subject I loved but could not pursue to university with Physics too!

Questions Sarah has answered

What is the difference between Transverse and Longitudinal waves?

Transverse Waves: Displacement of the medium is perpendicular to the direction of propagation of the wave.

To understand this it is good to think of a rope being held still by person B and being moved up and down by person A. The direction of propagation is from person A to B, so you will see the waves move along this way. But the displacement will be up and down.

Can travel in solids, but not in liquids and gas.

eg. Electromagnetic radiation

Longitudinal Waves: Displacement of the medium is parallel to the direction of propagation of the wave.

A good example for this is a slinky being pushed along the table, the propagation will be along the table and so will the displacement of all the 'rings'.

Can travel through all states of matter.

eg. Sound waves
