Index of Refraction and Speed of Light
Index of Refraction and Speed of Light
The index of refraction (n) of a medium is a measure of how much light slows down when passing through it. A higher index of refraction means light travels slower in that medium. The formula for calculating this is n = c/v, where c is the speed of light in a vacuum and v is the speed of light in the medium.
What happens when light enters a material with a higher index of refraction?
What happens when light enters a material with a higher index of refraction?
When light enters a material with a higher index of refraction, its speed decreases. As light transitions from a less dense medium to a denser medium, it bends towards the normal.
Polarizing Angle
Polarizing Angle
The polarizing angle, also known as Brewster's angle, is the angle of incidence at which light with a specific polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.

Study Notes
Refraction and Reflection
- Index of refraction less than 1 implies light speed in the medium is greater than in a vacuum.
- When light enters a material with a higher index of refraction, its speed decreases.
- The polarizing angle is also known as Brewster's angle.
- Light speed in a medium is related to its index of refraction (n = c/v).
Lenses
- Spherical lenses have both spherical and chromatic aberration.
- A concave mirror with an erect image larger than the object has a focal length that is related to the object and image distances by 1/f = 1/do + 1/di (where f is focal length, do is object distance, and di is the image distance.)
- A convex mirror produces virtual, upright, and reduced images.
Diffraction Gratings
- Diffraction gratings with more slits produce sharper diffraction orders.
- Diffraction gratings with the same slit separation, but different numbers of slits, produce different separation between orders which is impacted by the number of slits.
Speed of Light in Different Materials
- Diamond has the slowest speed of light.
- Light travels fastest in a vacuum.
Mirrors
- Rear-view mirrors on cars are generally convex; objects appear closer in convex mirrors.
- Light rays reflecting from a concave mirror meet at the focal point.
- Convex mirrors produce virtual, upright, and reduced images.
Interference and Diffraction
- Destructive interference occurs when the path difference is mλ/2, where m = 0, 2, 4, ...
- Bragg's law describes X-ray diffraction maxima: 2d sin(θ) = nλ.
- In a double-slit experiment, alternating light and dark bands are observed.
- Light rays are in phase if their electric fields are maximum simultaneously.
Optical Phenomena
- A prism refracts light, separating colors. Blue light is refracted more than red light.
- If an object is inside the focal point of a converging lens, the image is virtual.
- Total internal reflection occurs when the angle of incidence is greater than the critical angle. (Light is totally reflected)
- Chromatic aberration occurs because the refractive index of a material varies with wavelength.
Lens Characteristics
- A converging lens with a focal length of 50 mm and a required three-fold magnification of a virtual image will need a specific object location (object distance).
Additional Information
- X-ray diffraction is related to Bragg's law.
- For a thin film viewed in white light, the observed color depends on the thickness and the wavelength of reflected light.
- Double-slit experiments with different slit separations show varying maxima distances on the screen.
- The limiting angle of resolution is related to the pupil diameter, wavelength of light and the refractive index of the eye, determined by the formula.
- Liquid crystal displays use polarization and dichroism.
- Light refracts away from the normal when moving into a denser medium.
- The frequency of light has no effect on the angle of refraction in common transparent media.
- For objects placed at or near the image center of curvature of a concave mirror a larger image results.
- For objects placed at or near the image focal point of a double-concave mirror a diminished image results.
- Light traveling through air/vacuums has a different speed from light traveling through denser mediums (like water or glass). The relationship is described by index of refraction.
