Select from the dropdown lists to complete the text.

The phase angle can also be written as fractions of wavelengths, degrees or radians;
360 degrees = ( 1, 1/2, 1/4, 3/4 ) wavelength = ( 2n, 1/2n, 3/2n, 1n ) radians
180 degrees = ( 1/4, 1, 1/2, 3/4 ) wavelength = ( 3/2n, 2n, 1n, 1/2n ) radians
90 degrees = ( 1, 3/4, 1/4, 1/2 ) wavelength = ( 1/2n, 2n, 3/2n, 1n ) radians
270 degrees = ( 1/2, 1, 3/4, 1/4 ) wavelengths = ( 3/2n, 1n, 2n, 1/2n ) radians
