An illustration to show the respective wavelengths of electromagnetic waves. There is a transverse wave with really small wavelengths to really long and are listed from smallest to largest are gamma ray, x-rays, ultraviolet, visible, infrared, microwave and radio. Which has the longest wavelength? Which has the highest frequency?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
