Question 13

Q13) Define the following terms:

Amplitude, Time period, Frequency

  • Solution

  • Transcript

Solution:

  1. Amplitude : The maximum displacement of a wave on either side of its mean position is called amplitude. A = XY is amplitude

  1. Time period : Time taken to complete one vibration is called Time period, i.e from A to B

  2. Frequency : Number of oscillations made by a wave in one second is known as its frequency

hello welcome to Lido homework today we are going to define the following terms amplitude time period and frequency what the amplitude means what is the time period means what is the frequency means so I'm going to write down the definition of each one let's look here what amplitude means first so the amplitude amplitude amplitude means the maximum displacement of a wave on the other side of its mean position maximum maximum displacement displacement of a wave on either side of the position of either either side of its mean position the mean position is called amplitude so once again so it's called amplitude amplitude this is the amplitude the maximum displacement of a wave on either side of its main position is called the amplitude and what is the time period means so what the time period let's look here yes I'm going to change the color so it can be easy for you fine well it's okay that's what the amplitude card time period so the time is taken to complete time period time is taken to the time taken to complete time to complete one vibrate one vibration one vibration is called time period time taken to complete one vibration is called complete completion okay time taken to complete uh one vibration vibration is called time period so what is the another thing that is our left vision is frequency what the frequency means do with other color frequency means uh yeah it's fine yeah write down definition frequency frequency means what so number of oscillations made by a wave in one second number of oscillations made by a wave in one second in one second is known as frequency so this is only by frequency so I hope you understood this what is a frequency means what is the time period means and what is the amplitude means so thank you for watching this video subscribe to the channel for regular updates
