true, it does bend when it travles through water.
Light travels in the form of electromagnetic waves, moving at a speed of about 299,792 kilometers per second in a vacuum. It can also travel through various mediums, such as air, water, and glass, but its speed may vary depending on the medium's refractive index. The wave nature of light allows it to diffract, reflect, and interfere, creating the phenomena we observe in daily life.
Mainly electromagnetic waves, such as light.
