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.

If there are 50 people per square kilometer in a city, and the area of the city is 1.5 × 10 square kilometers. What is the total
qaws [65]

Answer:

750 people

Explanation:

From the question,

Number of people in the city = population density×Area of the city

N = D×A.......................... Equagtion 1

Where N = Number of people in the city, D = population density, A = Area of the city.

Given: D = 50 people per square kilometer, A = 1.5×10 square kilometer.

Substitute into equation 1

N = 50(1.5×10)

N = 750 people.

Hence the total number of people in the city is 750 people.
