## Study Notes

### Reflection and Its Principles

• Reflection occurs when light bounces off a surface, an example includes seeing your image in a mirror.
• Reflection of light is characterized by "angle of incidence" equaling "angle of reflection."
• The law of reflection states that the incident angle and the reflected angle are equal relative to the normal line at the surface.

### Application in Seismology

• Reflection is vital in seismology for studying seismic waves, allowing the interpretation of underground structures by analyzing wave behavior.

### Wave Equation and Its Applications

• The wave equation arises in fields such as physics and engineering, describing wave motion.
• It applies to various types of waves, including sound waves, light waves, and water waves.

### Electromagnetic Waves

• Special 'grazing' mirrors can reflect electromagnetic waves at shallow angles, including X-rays and gamma rays.
• The wave equation describes both mechanical and electromagnetic waves, conveying the relationship between wave displacement and time.

### Wave Equation Characteristics

• The order of the wave equation typically refers to the highest derivative present, which is usually second order for basic wave equations.
• The one-way wave equation is used to describe waves propagating in a single direction, such as in certain acoustic or electromagnetic applications.

### Standing Waves

• Standing waves are considered stationary wave patterns formed by the interference of two waves traveling in opposite directions, characterized by fixed nodes and antinodes.
