EM Waves

If you have any questions please post accordingly...

SPEED TEST
















Some Observations

• EM wave travels at the "speed of light", please understand that visible light itself is contained within the EM spectrum. It is more appropriate to state 3.0 x 10^8 m/s in vacuum.

• Q3, most of you understand that when frequency reduce, wavelength will increase, however they are not in a linear relationship. and the graph (graph a) should not touch x and y axis.

• Students like to write shortest "frequency" and longest "frequency" which is inappropriate, use lower or higher instead.
