Study Notes
Behavior of Monochromatic Light in Different Mediums
- Monochromatic light slows down and bends toward the normal when entering a denser medium from a less dense medium due to change in speed.
- In a denser medium, the speed of light decreases, leading to a shortening of the wavelength, while the frequency remains constant.
Refractive Index
- The refractive index (n) is defined as the ratio of the speed of light in a vacuum (c) to the speed of light in a specific medium (v): ( n = \frac{c}{v} ).
- A higher refractive index indicates a greater degree of bending of light as it passes into the medium.
Effects of Light Moving Between Media
- When light transitions from a denser medium to a less dense medium, it speeds up and bends away from the normal.
- Refraction is the cause of bending, influenced by the difference in light speed in the respective mediums.
Factors Influencing Speed and Wavelength in Densely Packed Mediums
- The decrease in speed and wavelength of light in a denser medium is due to interactions with the medium's particles, which absorb and re-emit photons, thus slowing their overall speed.
- The inertia and density of particles in the medium can impede light propagation.
Relationship Between Speed of Light and Refractive Index
- As refractive index increases, the speed of light in that medium decreases; conversely, a lower refractive index corresponds to a higher speed of light in the medium.
- The refractive index is a dimensionless number indicating how much light slows down compared to its speed in a vacuum.
