## Top best answers to the question «How to find a wave number from wavelength»

Wave number is expressed in reciprocal meters (m-1). The wave number for an EM field is equal to 2 pi divided by the wavelength in meters. (In some references, it is defined as the reciprocal of the wavelength in meters; in still others, it is defined as the reciprocal of the wavelength in centimeters.)

#### What are three ways to measure wavelength?

• Set up the ripple tank as shown in the diagram with about 5 cm depth of water.
• Adjust the height of the wooden rod so that it just touches the surface of the water.
• Switch on the lamp and motor and adjust the speed of the motor until low frequency waves can be clearly observed.
