Physics quantities and units
This video provides a brief introduction to the seven base units used in physics. Base units are identified with their symbols and S.I units.
The origin and definition of the metre is explained and reference to Wikipedia is made for definitions of the other base units....
Scalars and vectors
This video describes the key differences between vectors and scalars. It explains that vectors depend upon both magnitude (amount) and direction, whereas scalars are dependent upon magnitude and are independent of direction.
Examples of vector quantities are listed as: displacement, velocity, acceleration,...
Electromagnetic waves - wavelengths and frequencies
This video revises the order of electromagnetic spectrum (GCSE) and introduces the range of magnitudes of wavelengths and corresponding frequencies for each type of electromagnetic radiation.
Electromagnetic waves - why they are transverse
This video helps students to visualise the electric and magnetic field components of an electromagnetic wave.
The electric and magnetic oscillations (vibrations) are at 90⁰ to each other and also to the direction of energy propagation.
