has-large-font-size\">\n<li><strong>Vibration<\/strong> is the rapid back-and-forth movement of an object.<\/li>\n\n\n\n<li>Examples: A guitar string vibrating after being plucked, or a tuning fork set into motion.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color wp-elements-c76ce29a75520b21be5eb2047e09716d\" style=\"color:#000060\"><strong>Amplitude<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Definition<\/strong>: The <strong>amplitude<\/strong> is the maximum distance an object moves from its resting (mean) position during vibration.<\/li>\n\n\n\n<li>Represents the <strong>height<\/strong> of the wave produced by the vibration.<\/li>\n\n\n\n<li><strong>Higher amplitude<\/strong> means louder sound (for sound waves) or more energy.<\/li>\n\n\n\n<li><strong>Example<\/strong>: In a swinging pendulum, the amplitude is the maximum distance it swings away from its resting position.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-fea9fa922ae5ececf828980f93afdf90\" style=\"color:#000060\"><strong>Time Period<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Definition<\/strong>: The <strong>time period<\/strong> is the amount of time it takes for one complete cycle of vibration.<\/li>\n\n\n\n<li>Measured in <strong>seconds<\/strong> (s).<\/li>\n\n\n\n<li><strong>Formula<\/strong>: <\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\"><strong>Time&nbsp;Period (T) = 1 \/ Frequency<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Example<\/strong>: If a pendulum takes 2 seconds to complete one swing, its time period is 2 seconds.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-6e5581f48bd5d7e3ccb3f2c866257054\" style=\"color:#000060\"><strong>Frequency<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Definition<\/strong>: The <strong>frequency<\/strong> is the number of complete vibrations or cycles that occur in one second.<\/li>\n\n\n\n<li>Measured in <strong>hertz<\/strong> (Hz).<\/li>\n\n\n\n<li><strong>Formula<\/strong>: <\/li>\n<\/ul>\n\n\n\n<p class=\"has-text-align-center has-large-font-size\"><strong>Frequency (f) = 1 \/ Time&nbsp;Period<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Higher frequency<\/strong> means a higher-pitched sound or faster vibration.<\/li>\n\n\n\n<li><strong>Example<\/strong>: If a tuning fork vibrates 500 times per second, its frequency is 500 Hz.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color wp-elements-14ef70e51affb3a23a0b84ccc9d46cd7\" style=\"color:#000060\"><strong>Relationship Between Amplitude, Time Period, and Frequency<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Amplitude<\/strong> affects the <strong>loudness<\/strong> (for sound) but does not influence the frequency.<\/li>\n\n\n\n<li><strong>Time period<\/strong> and <strong>frequency<\/strong> are <strong>inversely related<\/strong>: when one increases, the other decreases.<\/li>\n\n\n\n<li>The <strong>energy<\/strong> of a vibration increases with <strong>higher amplitude<\/strong> but remains unaffected by changes in frequency.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color has-large-font-size wp-elements-80a2bf8d52929f3ceba1a31df2aae484\" style=\"color:#000060\"><strong>Real-Life Examples<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list has-large-font-size\">\n<li><strong>Musical instruments<\/strong>: The pitch of a note depends on the frequency of vibrations, while the loudness depends on the amplitude.<\/li>\n\n\n\n<li><strong>Seismographs<\/strong>: Detect the vibrations of the Earth to measure earthquake intensity using amplitude.<\/li>\n\n\n\n<li><strong>Clock pendulums<\/strong>: Operate on the principle of time period to keep accurate time.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading has-text-color has-link-color has-large-font-size
