Refraction is the change in direction of a wave of light passing from one object to another. How much a wave is refracted is determined by the change in wave speed and the initial direction of wave relative to the direction of change in speed.
Refraction is when light hits a transparent object (for example a glass) and slows down, as glass is a denser object than air. The rays will appear to bend, and this is called refraction.

Love your use of subject appropriate vocabulary Misha.

the straw can move direction and the water makes it look like it is bent
Refraction is when light travels differently through water so it changes the direction to make it appear bent.
