| 🇬🇧 | 🇬🇧 |
| How long are the wavelengths of electromagnetic waves of light? | 400 nm to 700 nm |
| Rarer to denser? | Towards the normal |
| Denser to rarer? | Away from the normal |
| What is the cause of refraction? | Change in speed of light while crossing two transparent media |
| What is free space? | Vacuum |
| Ratio of speed of light in vacuum to speed of light in a giver medium? | Refractive index/ Absolute refractive index |
| What is the S.I unit of refractive index? | Unitless quantity |
| Does the frequency of light keep on changing in different media? | No , it remains constant |
| Which light has maximum refractive index? | Violet light |
| What is relative refractive index? | Ratio of speed of light in two mediums |
| When can a light ray trace it's path back? | When it's final path gets reversed |
| What is the law for tracing back of the path of light called? | Principle of reversibility of the path of light |
| For a rectangular glass block, what is the relation between angle of emergence to angle of incidence? | They are equal |
| For a rectangular glass block, what is the direction of the emergent ray with respect to the incident ray? | They are parallel |
| Is the displacement between emergent ray and extended incident ray angular or lateral? | Lateral bishhhhhhhhhhhhhhh |
| Why is lateral shift more for violet light than red light? | Because refractive index of violet light is greater |
| Cooler air is an optically denser of rarer medium? | Optically denser medium |
| Hotter air is an optically rarer or denser medium? | Optically Rarer medium |
| What refraction does light entering the earth suffer? | Atmospheric refraction |
| Why will the said image be brightest? | Because it goes through maximum reflection and refraction |
| What happens to the images subsequently/successively from I2? | They keep on getting dimmer |
| In a prism, in what direction does the light ray bend? | Towards the base of the prism |
