Study Notes
Seismic Waves
- Seismic waves are vibrations generated by an earthquake, explosion, or similar energetic source and propagated within the Earth or along its surface.
Body Waves
- Body waves have two types: P-waves and S-waves.
- P-waves (Primary waves) can travel through solid and liquid and are faster than S-waves.
- S-waves (Secondary waves) can only travel through solid and are slower than P-waves.
- Body waves travel through the Earth's inner layers.
Surface Waves
- Surface waves are combinations of transverse and longitudinal waves.
- They can only travel through the surface layer (solid) and cause more damage than body waves.
- There are two types of Surface waves: Love waves and Rayleigh waves.
Love Waves
- Love waves have a horizontal motion and are the fastest surface wave.
- They are named after the British mathematician A.E.H. Love (Augustus Edward Hough Love).
Rayleigh Waves
- Rayleigh waves move the surface in a circular motion.
- They are named after the British physicist, Lord Rayleigh.
Reflection
- Reflection is the bouncing back of light or other waves when they encounter a surface that does not absorb them.
- The law of reflection states that when a ray of light is reflected off a surface, the angle of incidence is equal to the angle of reflection.
Types of Reflection
- Regular/Specular Reflection: Light or waves bounce off a smooth surface in a specific direction, creating a well-defined and organized image.
- Irregular/Diffused Reflection: Light or waves bounce off a rough or uneven surface, scattering in various directions, leading to a less organized and diffused image.
Mirrors
- Plane Mirrors: Flat and smooth reflective surfaces that reflect light, preserving the relative proportions and orientations of objects.
-
Characteristics formed by Plane Mirrors:
- Image: Virtual, appears to be located behind the mirror, even though there is no actual object or light source behind it.
- Orientation: Lateral inversion, or left-right reversal, of the image in a mirror due to the way light reflects off the mirror surface.
- Location and Size/Magnification: The size and distance of the object's reflection in the mirror appear the same as the size and distance of the actual object.
Curved Mirrors
-
Concave/Converging Mirrors:
- Shape: Curved inward, creating a surface that is reflective on the inner side.
- Reflective Properties: Can converge incoming parallel light rays to a focal point, resulting in real or virtual images.
- Uses: Can produce magnified images, used in applications like makeup mirrors, shaving mirrors, and some types of reflecting telescopes.
-
Convex/Diverging Mirrors:
- Shape: Curved outward, creating a reflective surface on the outer side.
- Reflective Properties: Diverge incoming parallel light rays, making the reflected rays appear to be coming from a virtual focal point behind the mirror.
- Uses: Provide a wider field of view, used in applications like side-view mirrors in cars, security mirrors, and in stores to eliminate blind spots.
