As discussed in Unit 10 of The Physics Classroom Tutorial, electromagnetic waves are waves that are capable of traveling through a vacuum. Unlike mechanical waves that require a medium in order to transport their energy, electromagnetic waves are capable of transporting energy through the vacuum of outer space. Electromagnetic waves are produced by a vibrating electric charge and as such, they consist of both an electric and a magnetic component. The precise nature of such electromagnetic waves is not discussed in The Physics Classroom Tutorial. Nonetheless, there are a variety of statements that can be made about such waves.

Maksim231197 [3]

Answer:

PRECAUTIONS FOR USING A SPECTROPHOTOMETER :

1 . By allowing the lamps and electronics to warm up

2.By cleaning up any spills inside the cuvette compartment

3.By carrying out the set-up procedure in the correct order

4.By ensuring that %T or transmission is used as appropriate

5.By closing the door to the cuvette compartment before reading the result

6.By performing calibration checks after set up

7.By wiping fingerprints and spilt sample off the outside of the cuvette before measuring

8.By using the correct wavelength

PRECAUTIONS FOR USING A FRAME PHOTOMETER:

1. Do not move or Carry the unit when in use or connected to the mains electricity supply

2. There should be sufficient time for the chimney to cool before handling

3. Do not use acetylene with the flame photometer

4. Over adjustment of the fuel valve will cause excess flame

Do not position the product so that it is difficult to disconnect from the mains supply

5. Do not cover the chimney whilst in use.

6. Do not block or obstruct ventilation slots /airways

7. Do not operate or handle any part of the product with wet hands

Describe three types of relationships between organisms found within an ecosystem. How is energy transferred in each type of rel

maks197457 [2]

Well, there's producers and consumers. There is also one provider that is the main source of energy for all living things which is the sun. The sun provides sunlight for the producers to make their own food through photosynthesis then consumers come and eat the producers(plants) and that gives them energy. And then predators come and eat that animal and that provides their energy.
