In the visible spectrum,which color,violet or red,undergoes greater refraction? Why?
(A) Violet light undergoes greater refraction than red light. This is because violet light has a shorter wavelength and higher frequency compared to red light.
| Color | Wavelength $(\lambda)$ | Frequency $(v)$ | Deviation |
|---|---|---|---|
| Violet | $400 \, nm$ | $7.50 \times 10^{14} \, Hz$ | Greater |
| Red | $750 \, nm$ | $4.00 \times 10^{14} \, Hz$ | Lesser |
