WebWhen you superimpose two sine waves of different frequencies, you get components at the sum and difference of the two frequencies. This can be shown by using a sum rule from trigonometry. For equal amplitude sine waves. The first term gives the phenomenon of beats with a beat frequency equal to the difference between the frequencies mixed.

WebAccording to wave-based theories, the light waves spread out from the source in all directions, and upon striking a mirror, are reflected at an angle determined by the angle at which the light arrives. The reflection process inverts each wave back-to-front, which is why a reverse image is observed. The shape of light waves depends upon the size ...

WebSound waves are longitudinal and this film shows how to make and demonstrate a transverse wave machine - but it’s just too good not to include here! The word “machine” probably gives the wrong impression - this machine is built simply and cheaply from duct tape, kebab sticks and jelly babies. WebWhat is SEN Support? SEN Support is the system by which schools should assess the needs of children, and then provide appropriate support.
