The typical wavelength of a gamma ray is very small, less than 1 x 10 to the negative 11th power, or 0.000000000001 meter. These rays have the shortest wavelength and the highest frequency of all forms of electromagnetic... More » Science Physics Optics & Waves

Gamma rays are used in many different ways; one of the most common uses is inspecting castings and welds for defects that are not visible to the naked eye. Another common use of gamma rays is in the treatment of certain ... More »

The benefits of gamma rays are most clearly seen in the medical field, where they are used to treat cancers and tumors. A technology called the gamma ray knife uses concentrated gamma ray beams to target and destroy canc... More »

The formula for finding the velocity of a wave is to multiply its wavelength by its frequency. In this case, 30 m x 12 Hz = 360 meters per second. More »

Pitch is determined by the frequency of a wave, and frequency is the combination of wavelength and speed at which the wave is traveling. Sound has a constant speed of 343 meters per second, so wavelength dictates pitch. ... More »

Parts of a transverse wave include the crest, trough, amplitude and wavelength. The crest is the top of the wave, and the trough is the bottom. The amplitude refers to the height of the wave from the midpoint, or rest po... More »

Gamma ray telescopes use special detectors to measure gamma radiation from stars. Unlike conventional telescopes, gamma ray telescopes don’t take pictures or use optics. Instead, they create maps of gamma sources based o... More »
