Amplitude of a wave is? - Answer-is the maximum height of the peaks or valleys Direct Proportional - Answer-as the energy increases the height increases. Period of a wave is? - Answer-the TIME required for one complete cycle Wavelength of a wave is? - Answer-the distance from ONE peak to the next peak. Inversely Proportional is? - Answer-As one increases the other decreases as velocity remains the same. A change in frequency causes a change in wavelength while ________ remains the same? - Answer-Velocity C-F (Lambda) When Frequency increases wavelength must decrease. Formual Can be changed. F= C/ Lambda or Lambda= C/F - Answer-C= velocity which is speed of light 3 X 10^8 F= Frequency Lambda= wavelength
