|---|---|---|
| x-rays | 1017 – 1020 | 1 nm – 1 pm |
| ultraviolet | 1015 – 1017 | 400 nm – 1 nm |
| visible | 4 – 7.5*1014 | 750 nm – 400 nm |
What is the frequency of violet light with a wavelength of 400nm?
Therefore the frequency of the violet light is 7.5*10¹⁴ Hz and its wave number is 2.5*10⁶ m⁻¹.
How do you calculate the wavelength of light?
How do you measure wavelength?
- Use a photometer to measure the energy of a wave.
- Convert the energy into joules (J).
- Divide the energy by Planck’s constant, 6.626 x 10-34, to get the frequency of the wave.
- Divide the speed of light, ~300,000,000 m/s, by the frequency to get wavelength.
What is the wavelength of light given energy 3.03 x10 ‘- 19j?
Expert-verified answer we have to find the wavelength of light. therefore the wavelength of light is 656 nm.
How do you solve for wavelength?
How to calculate wavelength
- Determine the frequency of the wave. For example, f = 10 MHz .
- Choose the velocity of the wave.
- Substitute these values into the wavelength equation λ = v/f .
- Calculate the result.
- You can also use this tool as a frequency calculator.

What is the wavelength of a photon emitted during transition from N 5 to N 2 in the hydrogen atom?
What is the wavelength of a photon emitted during a transition from n=5 state to n=2 state in the hydrogen atom? A. 434nm.
How do you calculate the frequency of a wave when given the wavelength?
If you want to calculate the frequency from wavelength and wave velocity:
- Make sure they have the same length unit.
- Divide the wave velocity by the wavelength.
- Convert the result to Hertz. 1/s equals 1 Hertz.
What is the frequency of violet light with a wavelength of 4000 A?
Solution : (a) `v = ( c)/(lamda) = (3 xx 10^8)/(4000 xx 10^-10) = 7.5 xx 10^14 Hz` (b) `v = ( c)/(lamda) = (3 xx 10^8)/(8000 xx 10^-10) = 3.75 xx 10^14 Hz`.
