How does frequency influence the refraction of waves?

Frequency does not significantly influence the refraction of waves; it's the speed and wavelength that are primarily affected.

Refraction is the bending of waves when they enter a medium where their speed is different. This phenomenon is commonly observed with light waves, but it also applies to other types of waves like sound and water waves. For a deeper understanding of this, explore the principles of refraction. The degree of bending, or refraction, is determined by the change in speed of the wave, which is influenced by the properties of the medium, not the frequency of the wave.

The frequency of a wave is defined as the number of wave cycles that pass a fixed point per unit of time. When a wave enters a new medium, its frequency remains constant. This is a consequence of the principle of conservation of energy. The energy of a wave is directly proportional to its frequency, and since energy cannot be created or destroyed, the frequency of the wave cannot change as it moves from one medium to another.

However, while the frequency remains constant, the speed and wavelength of the wave do change when the wave enters a new medium. The speed of the wave is determined by the properties of the medium. For example, light waves travel faster in air than in water or glass. When the speed changes, the wavelength of the wave also changes in order to maintain the constant frequency. Understanding wave parameters can provide further insights into this phenomenon. This change in speed and wavelength is what causes the wave to bend, or refract. It's also beneficial to know about the different types of waves to appreciate the diversity in wave behaviour across mediums.

IB Physics Tutor Summary: In summary, the bending or refraction of waves, such as light or sound, is mainly due to changes in their speed and wavelength when they move into a different medium, not their frequency. Frequency stays the same due to energy conservation, but the speed and wavelength adjust according to the new medium, leading to the refraction phenomenon.
