Final answer:
Explanation on reflection in mirrors and sound waves produced by a guitar string.
Explanation:
The law of reflection states that waves reflect off surfaces at the same angle they strike the surface. In an unbroken mirror, the surface is smooth relative to the wavelength of waves, allowing for regular reflection. However, in a broken mirror, the irregular surface causes scattering of waves, making it difficult to see a clear reflection.
Sound waves with different frequencies can be produced by the same guitar string due to harmonics and overtones. When a guitar string vibrates, it produces not only its fundamental frequency but also multiples of that frequency, creating different tones. This phenomenon is key to the variety of sounds produced by a guitar.
