Answer:
Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.
Answer:
They both arrive at 1:00 PM
Explanation:
Amount Davien has to drive : 40km
Amount Jackson has to drive = 50km
Davien moves at 40km/h,
Therefore, it only takes Davien 1 hour to get there.
12:00 PM + 1 hour = 1:00 PM
Jackson moves 100km/h
He needs to drive 50 min, so 50/100 = 1/2
It takes him half an hour, or 30minutes
If he leaves at 12:30, then he gets there at 1:00 PM
The photoelectric effect supports a particle model of electromagnetic radiation as it behaves like an elastic collision between two particles.
<h3>What is Photoelectric effect?</h3>
This is defined as the emission of electrons when electromagnetic radiation, such as light, hits a material.
The energy of a wave increases with an increase in intensity and in photoelectric effect. However intensity has no effect on the energy of electrons emitted which is why it is inadequate to explain the photoelectric effect.
