Scientists have achieved what once seemed impossible, sending signals backward through time using a groundbreaking electromagnetic experiment.

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time reversal' doesn't involve historical travel but reverses a wave's sequence, ...

Straight wave reflection from straight barriers, 80-231, approx 3 minutes Single straight pulses are reflected from a straight barrier placed parallel to the wave front, then at 35, 45 and 55 degrees.

To investigate the reflection of light by a plane mirror.

the incident ray with a cross the ray that leaves the block with two crosses - one near the block and the other further away Remove the block. Join the crosses to show the paths of the light rays.
