If you calibrate your intuition so that you expect large frequencies to be paired with short periods, and vice versa, you may avoid some embarrassing mistakes on physics exams. The horizontal axis represents time.įor example, if a newborn baby’s heart beats at a frequency of 120 times a minute, its period (the interval between beats) is half a second. Sinusoidal Waves of Varying Frequencies: Sinusoidal waves of various frequencies the bottom waves have higher frequencies than those above. Note that period and frequency are reciprocals of each other. Frequency is usually denoted by a Latin letter f or by a Greek letter ν (nu). The frequency is defined as the number of cycles per unit time. ) One complete repetition of the motion is called a cycle. (The symbol P is not used because of the possible confusion with momentum. The usual physics terminology for motion that repeats itself over and over is periodic motion, and the time required for one repetition is called the period, often expressed as the letter T. Higher deflections are available on application.įinish: Springs and metal isolator bodies are epoxy powder coated, rated at 1000 hours salt spray testing as per ASTM B117.\) Standard Deflection: Isolators are available with spring deflections of 25mm and 50mm at rated load as standard.
