True or false 1.) the greater the frequency of the wave is a particular medium, the greater the wavelength of the wave 2.) radio waves are an example of mechanical waves. 3.) light waves are examples of transverse waves. 4.) the energy of mechanical wave depends on the frequency of the wave. 5.) as the period of a wave increases, the frequency increases. 6.) when a wave reflects from fixed boundary, the only change in the wave is the direction of travel. 7.) two waves cannot occupy the same space at the same time. 8.) if two tuning forks of different frequencies are struck at the same time, you will hear beats as the result of constructive interference followed by destructive interference.

Find the true statement. use the underlined word to determine whether the statement is true or false. question 3 options: electromagnetic waves are mechanical because they require a medium to travel. electromagnetic waves are transverse because they have electric and magnetic fields that move perpendicular to the direction of energy transfer. the speed of an electromagnetic wave depends on the frequency of the wave. gamma rays are faster than radio waves. as the frequency of an em wave increases, so does the wavelength. they are directly related.
