Due to the photon's energy, which is higher in blue light than green. When you point to the right, you can see that blue light can produce bigger amounts of energy than green light now does. The current of blue light is, therefore, greater than that of green light. Wit, Gore predicts that we will have most of the color violet and the least of the color red. Violet has more energy, and as we descend, energy declines since blue have more energy.

What is the photoelectric effect and how did it change our concept of light and matter?

Heinrich Rudolf Hertz, a German physicist, developed the photoelectric phenomenon in 1887. Hertz discovered that when ultraviolet light shines on two metal electrodes with a voltage put across them, the light alters the voltage at which sparking occurs. This discovery is related to his work on radio waves.

What colors of light would cause the photoelectric effect?

The photoelectric effect refers to the finding that, under some circumstances, light striking a metal surface can result in the ejection of electrons. The light in the animation gains energy as it transitions from red to orange to yellow to green to blue.

2. If Peter is traveling .25 m/s on his bike, how long will it take him to reach
Semmy [17]

Answer:

48 seconds

Explanation:

Since S=d/t, plug in the known values and solve

0.25m/s=12m/t

0.25m/s*t=12m

t=12m/0.25m/s

t=48 seconds

You observe that a negatively charged plastic pen repels a chargedpiece of magic tape. You then observe that the same piece of t
swat32

According to the statement there is a force of repulsion between the two objects. Remember that two objects must have the same charge so that they repel each other. In this way if the tape is repelled by a plastic pen that is negatively charged, this allows us to appreciate that the tape is also negatively charged. Now if the tape repels the sphere, therefore the sphere is also negatively charged.

Under these considerations the correct answers would be

2. Sodium ions from the salt water on your hand moved onto the sphere

4. The excess negative charge from the sphere spread out all over your body

6. Electrons from the sphere moved into the salt water on your skin, where they reacted with sodium ions

7. After you touched it, the metal sphere was very nearly neutral.
