Hey, brainy squad. Light bulb ready to test your physics power. Today's quiz is all about wave. Are you ready? One. The distance to complete one vibration is called Frequency. Time period. Amplitude. Displacement. Time period is correct answer. Two. The maximum displacement from mean position is time period frequency amplitude displacement amplitude is correct answer three the time to complete one vibration is called time period frequency amplitude displacement time period is correct Answer four. Number of vibrations per second is Time period. Frequency. Amplitude. Displacement. Frequency is correct answer. Five. The waves that require medium for propagation. Mechanical waves. Electromagnetic waves. Both. None. Mechanical waves is correct answer. Six. Direction of vibration is perpendicular to direction of propagation in Transverse waves. Longitudinal waves. Both. None. Transverse waves is correct answer. Seven. Water waves and sound waves are examples of Electromagnetic waves. Mechanical waves, Longitudinal, None. Mechanical waves is correct answer. Eight. X-rays and radio waves are Electromagnetic waves. Mechanical waves. Both. None. Electromagnetic waves is correct answer. Nine.
