1. What does wavelength refer to? 2. What's the highest part of a wave called? Lowest part?
3. The longer the wavelength the the total energy of the wave.
4. The faster the frequency the the total energy of the wave.
5. Longer Wavelength + Lower Frequency =
6. The collection of all known frequencies and wavelengths of electromagnetic radiation is called what?
7. What waves are used for communication applications in television, radar, and mobile phones?
8. Which waves cause your skin to burn when you spend too much time in the sunlight?
9. What portion of the electromagnetic spectrum can be seen by humans?
10. Which color light has the shortest wavelength?

1. wavelength is the distance between two corresponding points on a wave

2. highest = crest, lowest = trough

3. lower

4. higher

5. this could tell you lots of things but given the context of the other questions I would say low energy or if it is asking what kind of wave, then probably radio waves.

6. Electromagnetic spectrum

7. radio waves

8. Ultraviolet

9. Visible light spectrum

10. violet

P.S. this is science (physics) not social studies

in this scenario it would be the consumer demand as most influential in making the decision. the band members need to figure out where and from whom they will make the most money, in other words who out of the two consumer groups - football fans or car drivers - will spend their money, who is more likely to contribute to their cause and buy what they are offering.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
