To change the frequency would mean to have more or less cycles per second. This would require manipulating time, which isn't the case here.
refraction
Refraction is the change in direction of a wave as it passes from one medium to another. This change occurs because the wave changes speed when it moves from one medium to another, causing it to bend.
When a wave refracts as it moves from one medium to another, its wavelength typically changes while its frequency remains constant. The change in wavelength is due to the change in speed of the wave in the new medium, as dictated by Snell's Law. The frequency remains constant because it is a characteristic of the source of the wave and does not change as the wave passes through different mediums.
When a wave passes from a less dense medium to a more dense medium, its speed decreases while its frequency remains unchanged. Additionally, the wave may also experience refraction, causing it to change direction.
When a wave passes from a less dense medium to a more dense medium, it generally slows down and changes direction. This change in speed and direction is called refraction. The wave may also experience a change in wavelength and frequency.

The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.

When a wave passes from a less dense medium to a more dense medium, its speed decreases while its frequency remains unchanged. Additionally, the wave may also experience refraction, causing it to change direction.
When a sound passes from one medium to another of different [non-zero] density, its speed and wavelength change, but its frequency doesn't. It doesn't matter what either medium is, or what source produced the sound.
When a wave passes from a less dense medium to a more dense medium, it generally slows down and changes direction. This change in speed and direction is called refraction. The wave may also experience a change in wavelength and frequency.
refraction
Light changes speed and direction as it passes from one medium to another due to the change in density between the two media. This change in speed and direction is known as refraction.
The bending of a wave as it passes from one medium to another is called refraction. This phenomenon occurs due to a change in the wave's speed as it enters a different medium with a different density.
When a light wave travels from air into water, its frequency remains unchanged. This is due to the fact that the frequency of a wave is determined by the source that creates it, and does not change when it passes from one medium to another.
a denser medium hav more no.of particles also > the no.of particles > the opposition provided for..... therefore both wavelength and speed of light changes but frequency remains the same.
