Need some help answers these

s below. Note that this is a PreLab. It must be turned in at the start of the lab period. Time cannot be given during the lab activity for PreLab work. After the start of lab activities, PreLabs cannot be accepted. 01. What is the meaning of the natural frequency of a physical system? Give an example of a physical system that exhibits its natural frequency. Q2. What is resonance? Give an example of a physical system in resonance. Q3. How are the speed and the frequency of a wave related? Q4. What is a standing wave? Give an example.

Explanation / Answer

C.) Freq. =( Speed of light / wavelength) speed of a wave is equal to the freq. Of that wave multiplied by the wavelength.

D). When the waves of same freq. And amplitude traveling in opposite direction meets each other then standing waves are produced.

Example:- waves produced by a string of guitar and various other musical instruments.

B). Resonance is a phenomenon in which a vibrating system or other forces drive another system to oscillate with greater amplitude at specific frequencies.

Example : - pushing a person in a swing is a common example and pendulum swing is another .

A). Natural freq. Is that freq. Of a system at which a system is allow to oscillate in absence of any external force.
