What characteristic of electromagnetic waves allows them to change trajectory when interacting with matter?
Understand the Problem
The question is asking which specific characteristic of electromagnetic waves is responsible for their ability to change direction when they interact with different materials. This involves understanding the properties of electromagnetic waves and how they behave upon interaction with matter.
Answer
Refraction allows electromagnetic waves to change trajectory when interacting with matter.
The characteristic of electromagnetic waves that enables them to change trajectory when interacting with matter is refraction.
Answer for screen readers
The characteristic of electromagnetic waves that enables them to change trajectory when interacting with matter is refraction.
More Information
When electromagnetic waves move from one medium to another, their speed changes, leading to refraction. This bending is why objects might appear in different positions underwater.
Tips
A common mistake is confusing refraction with reflection. Refraction involves a change in the wave direction due to speed change, not just a bouncing off surfaces.
