While light travels in a straight line and passes from one medium into another, for example from air to water, it will change speed and change direction. This is called refraction. The speed of light will change depending on the medium it travels through. The constant (the c in E = mc 2) is the speed of light in a vacuum.

Reflection of a sound wave occurs when the wave passes between two tissues of different acoustic impedances and a fraction of the wave 'bounces' back. This forms one of the major principles of ultrasound imaging as the ultrasound probe detects these reflected waves to form the desired image.
