The law of diffraction states that when a wave encounters an obstacle or aperture, it will bend around the edges of the obstacle or aperture and spread out into the region behind it. This bending and spreading out of the wave is known as diffraction. The amount of diffraction that occurs depends on the size of the obstacle or aperture and the wavelength of the wave.

Law of Refraction (Snell's Law)

When a wave traveling in one medium crosses a boundary into another medium with a different wave speed, it changes direction at the boundary. The law of refraction, also known as Snell's law, describes the relationship between the angle of incidence, the angle of refraction, and the indices of refraction of the two media.

The law of refraction states that:

```
n1 - sin(θ1) = n2 - sin(θ2)
```

where:

- n1 is the index of refraction of the first medium
- θ1 is the angle of incidence (the angle between the incident wave and the normal to the boundary)
- n2 is the index of refraction of the second medium
- θ2 is the angle of refraction (the angle between the refracted wave and the normal to the boundary)
