What is the difference between reflection and refraction? 

• Both involve light bending through a medium
• Reflection is light bouncing off a medium's surface and refraction is light bending through a medium
• Reflection is light bending through a medium's surface and refraction is light bouncing off a medium
• Refraction is light being absorbed in a medium and reflection is light being bent through a different medium

• it refracts light.

• it reflects light.

• it absorbs light.

• it has potential energy.
