Common Misconceptions Map — Refraction of Light
The map in words
- Refraction Misconceptions
- Speed and Frequency
- Frequency changes in medium
- Only speed and wavelength change
- Frequency depends on source
- Direction of Bending
- Light always bends
- No bending at normal incidence
- Speed changes even at 0 degrees
- Total Internal Reflection
- Wrong direction possible
- Must go denser to rarer
- Both conditions required
- Apparent Depth
- Always less than real
- Can be more if viewed from denser
- Depends on direction
- Refractive Index
- Always greater than 1
- Relative n can be below 1
- Optical vs physical density
- Glass Slab
- Emergent parallel to incident
- Lateral shift has 3 factors
- Not parallel to refracted ray
- Prism Deviation
- Deviation always increases with i
- U shaped i delta graph
- Minimum deviation position
- Speed and Frequency
Refraction of Light — Chapter Overview
The map in words
- Refraction of Light
- Laws of Refraction
- Snell's Law
- sin i divided by sin r equals n
- Coplanarity Law
- Incident Refracted Normal same plane
- Snell's Law
- Refractive Index
- n equals c divided by v
- Absolute always ≥ 1
- Depends on Density
- Depends on Temperature
- Depends on Wavelength
- What Changes
- Speed changes
- Direction changes oblique
- Wavelength changes
- Frequency stays same
- Glass Slab
- Lateral Displacement
- Incident parallel to Emergent
- i equals e always
- Prism
- Angle of Deviation
- Minimum Deviation
- Dispersion VIBGYOR
- mu equals sin A plus delta min by 2 divided by sin A by 2
- Apparent Depth
- n equals R divided by A
- Object in denser appears raised
- Apparent Shift equals R times 1 minus 1 by n
- Total Internal Reflection
- Critical Angle
- n equals cosec ic
- Glass 42 degrees
