Lowering the pH of a medium, such as a liquid, will not have a direct effect on the angle of refraction of light. The angle of refraction of light is primarily determined by the refractive index of the medium, which is not inherently influenced by pH changes. However, extreme changes in pH may induce changes in the optical properties of the medium, potentially leading to alterations in the refraction of light.
Refraction is caused by light crossing from one medium to another.

The speed.
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of refraction.

When light enters a different medium (refracts), its speed changes.
Yes. The speed of light in a vacuum (or space) is 3x10^8 m/s. Light will travel slower in any other medium.

The speed of light changes when it goes from one medium to another one with a different index of refraction. The angle of incidence doesn't influence the change in speed.
Refraction is caused by light crossing from one medium to another.
When temperature rises, the density of the medium changes. Speed of light through a medium is inversely proportional to the density of medium. So when the temperature increases, the density decreases and the speed of light in that medium increases. Note that this is the indirect effect of temperature. If light is travelling through vaccuum , then the temperature will have no effect on the speed of light.
this process is called refraction and usually happens when light changes medium eg from air to water or into a prism :)
