What is the frequency of a blue light whose wavelength is 450 nm?
What is the frequency of a blue light whose wavelength is 450 nm?
14 Hz
The frequency of blue light that has a wavelength of 450 nm is 6.7×1014 6.7 × 10 14 Hz.
What is the energy of a photon of blue light with a wavelength of 450 nm?
4×10−19J.
What is the wavelength of blue LED?
Narrow-spectrum blue light (also called blue LED light or short-wavelength LED light) is a type of high-energy visible light, defined as having a wavelength between 400 and 450 nm. This light is common in LEDs (even when used in illumination products) as a carry-over from computer-screen technology.
What color has a wavelength of 480 nm?
Color Physics
| Color | Wavelength (nm) |
|---|---|
| Green | 490 – 530 |
| Blue | 460 – 480 |
| Indigo | 440 – 450 |
| Violet | 390 – 430 |
How do you calculate the wavelength of blue light?
Since we are given wavelength we can use this equation: c= λ v where c is the speed of light (3 x 108 m/s), λ is the wavelength, and the v is the frequency (units: 1/s).
What energy does a wavelength of 450 nm have?
What is the energy of a photon of blue light λ 450 nm and of a photon of red light λ 700 nm in units of eV 1.6 * 10/19 J?
What is the energy of a photon of blue light (λ = 450 nm) and of a photon of red light (λ = 700 nm) in units of eV = 1.6*10-19 J? Solution: E = hc/λ.
How do you calculate blue light?
What does NM mean in LED lights?
LEDs are highly monochromatic, emitting a pure color in a narrow frequency range. The color emitted from an LED is identified by peak wavelength (lpk) and measured in nanometers (nm ).
What color is 400 nm?
