When we explore waves in Grade 11 physics, it’s really interesting to learn about some important qualities: wavelength, frequency, and amplitude. Let’s break these down in simple terms.
Wavelength: This is the distance between two wave points that are matching up, like the space from one high point (crest) to the next in a transverse wave, or from one compressed part to the next in a longitudinal wave. Wavelength is often shown with the Greek letter lambda (λ). If the wavelength is longer, that usually means the frequency is lower.
Frequency: This is about how many waves pass by a point in one second. We measure it in hertz (Hz). You can think of frequency like how busy a wave is—if it’s a higher frequency, that means lots of waves go by quickly, while a lower frequency means fewer waves. We can relate wavelength and frequency with this formula: ( f = \frac{v}{\lambda} ). Here, ( f ) is frequency, ( v ) is wave speed, and ( \lambda ) is wavelength.
Amplitude: This tells us how tall the wave is from its normal position to its highest point (crest) or lowest point (trough). In simple words, amplitude shows us the energy in the wave; bigger amplitudes mean more energy, which often means louder sounds or brighter light.
Understanding these properties helps us learn how waves act in different materials and situations!
