    What experiment i can do to see the laws of reflection for electromagnetic waves?

    I did an experiment that included a transmitting antenna, a receiving antenna and an aluminum plate. aluminum plate is a reflector is almost ideal.

    I wanted another one that could also check the same.

    Probably the simplest thing is to use coax transmission line, a pulsed voltage source and an oscilloscope. A a 50 Ohm RF coaxial cable and 100 MHz analog scope works well. You can terminate the end with resistors (50 ohm, open, shorted etc.) and demonstrate the laws of reflection.

    You can also easily measure the speed of transmision which is about 2/3 the speed of light in vacuum.
