Waves in water are transverse. This means that the vibrations causing the waves are perpendicular to the direction of energy transfer. As this little boat demonstrates, you can see that the waves are ...

Atmospheric scientists trying to pin down how clouds curb the amount of sunlight available to warm the earth have found that it depends on the wavelength of sunlight being measured. This unexpected ...

A ripple tank can be used to measure and calculate frequency, wavelength and the speed of waves on the water's surface. A ripple tank is a transparent shallow tray of water with a light shining down ...
