The energy wavelength equation is: E = hc/I, where E indicates energy measured in joules, I indicates wavelength in meters, c is the constant for how fast electromagnetic radiation (light for all extensive purposes) trav... More » Science Physics Optics & Waves

To calculate wave frequency in physics, one must know about the variables used in different formulas. One formula states that frequency (f) is equal to the wave velocity (v) divided by the wavelength (??????), or f = v/ ... More » Math Statistics

The amplitude formula for a wave is amplitude (a) = distance traveled by the wave (d) / frequency of the wave (f). The amplitude is the maximum height observed in the wave. Amplitude is measured in decibels (dB). More » Science Physics Optics & Waves

Infrared is energy with a longer wavelength than visible light, existing just outside the range of human vision. The sun is a natural source of infrared energy, as well as many other forms of energy from across the elect... More » Science Physics Optics & Waves

Wien’s law, also known as the displacement law, reveals the wavelength at which any object emits the majority of its energy. The formula used to calculate the wavelengths using Wien’s law is λmax (wavelength) equals 3 x ... More » Science Physics Optics & Waves

The basic properties of light are its wavelength, frequency, energy and speed. Light is composed of energy particles called photons and can behave as either a wave or as separate particles. More » Science Physics Optics & Waves

Light is composed of photons, which are discrete collections of energy with wave and particle properties, while sound travels as a wave through a medium, which makes it travel more slowly. While light and sound have some... More » Science Physics Optics & Waves
