Longitudinal waves move parallel to the direction of the wave 10 of 16 What happens when light passes through convex and concave lenses Convex converges rays of light that are parallel to to its principal axis. concave magnify and diverges straight lines 11 of 16 Difference between light and sound waves light is a transverse wave and sound is longitudinal 12 of 16 frequency and pitch Frequency is the number of cycles in a wave for a second. Pitch is our interpenetration of the frequency of a sound wave 13 of 16 What the decibel scale measures measure different levels of sound and which ones are safe and harmful. 14 of 16 purpose of battery in a circuit Battery is the main source of energy that provides voltage which allows the current to flow through. 15 of 16 what anmeter measures anmeter measures the current 16 of 16
