How to calculate the wavelength in nm?
How do you find wavelength in NM? c=λν c is a constant. Frequency has a unit of 1/s , which means 1 cycle per second. λ=cν What is the wavelength of light in nanometers (nm) that has a frequency of 5.71×1014Hz ? Given/Known: Equation: λ=cν=3.00×108m/s5.71×10141/s=5.25×10−7m.
What is the equation to calculate wavelength?
To calculate wavelength, use the formula wavelength = speed divided by frequency. Just plug in the wave's speed and frequency to solve for the wavelength. Remember to use the correct units when you're using the formula and writing your answer.
How do you calculate the wavelength of a wave?
To calculate the wavelength of a radio wave, you will be using the equation: Speed of a wave = wavelength X frequency. Since radio waves are electromagnetic waves and travel at 2.997 X 10^8 meters/second, then you will need to know the frequency of the radio wave.
How do you calculate energy from wavelength?
Multiply the speed of light and the Planck constant, and divide the product by the wavelength to calculate the photon energy. For example, yellow visible light photons have a wavelength of about 580 nm or 5.8E-7 m. Thus, their energy is 299,792,458 m/s x 4.13566733E-15 eV s/5.8E-7 m = 2.14 eV.
