There is some other formula. I google "k-alpha x-ray energy"and wikipedia tells me the answer straight away. You can do that too !Raghav Gupta said:Homework Statement

How to calculate momentum?
Or is there some other formula?
Oh, so that is Moseley's formula. Never seen that.BvU said:There is some other formula. I google "k-alpha x-ray energy"and wikipedia tells me the answer straight away. You can do that too !
The ratio of wavelengths is a comparison of the lengths of two different waves. It is typically expressed as a fraction or decimal and is used to describe the relationship between two wavelengths.
The ratio of wavelengths can be calculated by dividing the longer wavelength by the shorter wavelength. For example, if one wavelength is 600 nanometers and the other is 400 nanometers, the ratio would be 600/400 or 1.5.
The ratio of wavelengths is important in science because it can provide valuable information about the properties of waves. It can be used to determine the frequency, speed, and energy of a wave, which can help scientists better understand natural phenomena and develop new technologies.
The ratio of wavelengths can affect the color of light because different wavelengths correspond to different colors on the visible light spectrum. For example, shorter wavelengths appear as blue or violet light, while longer wavelengths appear as red or orange light. The ratio of these wavelengths determines the overall color of the light we see.
Yes, the ratio of wavelengths can change depending on the medium through which the wave is traveling. For example, the ratio of wavelengths of visible light will change when passing through a prism, resulting in the separation of colors. Additionally, the ratio can also change when a wave enters a different medium, such as when light travels from air into water.
