Answer:
Explanation:
The wavelength is the distance between two adjacent wavefronts. ... If the wave crosses to the new medium at an angle (not 90 degrees), the change ... When light enters a more optically dense medium, it is refracted closer to the normal. the same as the critical angle, light will travel along the boundary of the 2 mediums.

Lower the melting point
Explanation:
Salts helps to melt road by lowering the melting point. It acts as an impurity and generally, impurities low the melting point of substances.
Salts are used as an antifreeze. 
- Water freezes at 0°C and forms ice/snow which can impede human and vehicular movement. 
- When salt is added, it causes the depression of the freezing point by lowering it further. 
- The freezing point is pegged back at -6°C. 
- This way it takes more low temperature to freeze the water. 
- The salt acts as an impurity and causes the depression of melting point and widening of the melting range.
