Best Answer

Speed (of a wave) = frequency x wavelengthTherefore, you have to:

* Convert the wavelength to meters.

* Divide the speed of light - which is 300 million meters/second - by this wavelength.

The answer will be in Hz.

The frequency of light can be calculated using the formula: frequency = speed of light / wavelength. Plugging in the values gives us a frequency of approximately 474 THz (terahertz).

I suppose that you think to nanometers (nm) and not mm.
The frequency is 4,7361.10e14 Hz.

How could you use the diffraction of a laser beam by a slit to determine the wavelength of the laser light?

You can measure the diffraction pattern produced by the laser beam passing through a slit and use the formula for single-slit diffraction to determine the wavelength of the laser light. By analyzing the spacing between the diffraction fringes, you can calculate the wavelength of the light based on the angle of diffraction and the slit width.


How many pounds are in 633kg?

It is equal to 1395.52 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.


What is the mean property of he-ne laser?

The mean property of a helium-neon (He-Ne) laser is its ability to produce a coherent beam of light with a specific wavelength in the red spectrum (around 632.8 nm). This laser is known for its reliability, long coherence length, and low divergence, making it suitable for applications such as alignment, interferometry, and barcode scanning.


How much 16MM rebar in 1 ton?

In a ton of 16mm rebar, there are approximately 79 pieces of rebar. The weight of 16mm rebar is about 1.58kg per meter, so in a ton (1000kg), there are roughly 633 meters of 16mm rebar.


How many Nuclear plants are in Germany?

Germany has eight nuclear power plants in operation as of 2021. The country has made a decision to phase out all nuclear power plants by 2022 as part of its energy transition towards renewable energy sources.
