If the light is traveling straight up, then it hits the interface (surface
or boundary) between water and air perpendicularly (90° to the surface).
This direction is the direction of the 'normal' to the surface. So the
angle of incidence is zero, and that means the angle of refraction is
also zero. The light just keeps going in the same direction when it
emerges into the air, and is not bent.
However, its speed increases in air, and that means its wavelength
also becomes longer than it was in the water.
Answer:
In this type of pollution, the source and of the pollution, the source of the is single and identifiable.
Explanation:
These sources are regulated by federal and state agencies and include conduit pipes, industrial discharge and sewerage treatment plants that release treated or untreated waste matter in to water bodies. They can therefore possibly be directly controlled by human decision.
Answer:
the pilot should recourse back to the airport it og was in
Explanation:
Explanation:
Since less effort is needed in lifting a load to a higher level by moving over an inclined plane as compared to that in lifting the load directly, an inclined plane acts as a force multiplier. This is because the mechanical advantage of an inclined plane is always greater than 1.
