It’s due to the refraction of light rays as they traverse the boundary between water and air. The greater the viewing angle, the more the bending of the light and therefore the less the apparent depth. An object placed in a denser medium, when viewed from rarer medium appears to be at a lesser depth than its real depth due to refraction of light.
Answer:
B
Explanation:
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus.
Snell's law.
1=incident
2=refracted
Since it's coming out of the amethyst into air:
n1=1.55
n2=1.0003
=
°
Substituting back into Snell's equation we get
so the angle is
°
a) Evaporation occurs at room
temperature only.
- Reason: Evaporation occurs at each and every temp. because of the molecules of the solution have kinetic energy than the others, and thus they will evaporate leaving them behind.
