\u00a9 2020 wikiHow, Inc. All rights reserved. From the formula, it can be interpreted, that an electron having a higher velocity (or momentum) will have a shorter wavelength and vice versa. Remember to use the correct units when you're using the formula and writing your answer. This article was co-authored by Meredith Juncker, PhD. With the help of his experiments on Photoelectric effect, he was able to derive the value of Planck’s constant which came out to be 6.6 × 10. Wavelength usually is expressed in units of meters. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. Wavelength is commonly represented by the Greek letter lambda. For example: Find the wavelength of a wave traveling at 20 m/s at a frequency of 5 Hz. They travel with the speed of light in vacuum. wikiHow is where trusted research and expert knowledge come together. What is the speed of a sound wave that is 30Hz and has a wavelength of 5M? An electron is usually represented by the letter ‘e’. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Thanks! Electrons are the subatomic particles that carry a negative charge. The energy of a photon is usually given to solve these types of problems. Wavelength = 5M. Their mass is negligible. In quantum physics, we consider that every electromagnetic radiation is made up of small packets of energy called ‘quanta’. Question 1: Find the wavelength of an electron moving with a speed of ms-1. For example: Find the speed of a wave with wavelength 450 nm and frequency 45 Hz. Contributing Authors. The main postulate of his theory was that the energy of light is related to its frequency. The speed of light never changes, so v will always equal 3.0 x 10^8 m/s. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.

Calculating wavelength is dependent upon the information you are given. Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. This helped me a lot to learn, "This article helped me with understanding more about how the formula works. Quantum mechanics explains that light has a dual nature.
