Please I need someone to do this for me clearly.

Faraday's Law - Induced Currents and Induced Electric Fields -Prelab Name: Date: Lab day & time:- Question: How can a magnetic field produce a current? Part P- 1: The Galvanometer Previously. you have used the built in functions of digital multimeters to serve as a voltmeter or ammeter. In those cases you learned how to avoid damaging the equipment before you started the lab. Therefore, before starting this lab let's investigate how a galvanometer works. A galvanometer is shown in the picture to the right. The galvanometer is designed to measure miniscule values of current and because of that many galvanometers do not have units on their face. 1. Why would it be advantageous, to measure miniscule measure levels of current in this lab. Explain your answer with your knowledge of physics and justify your answer based on what you will be asked to do in this lab. 2. What kind of measurement issues could you have when using a galvanometer? Consider how fast small evels of current might change. Make sure you explain your answer. How could you damage your galvanometer and how could you avoid this? Explain your answer. 3.

Explanation / Answer

1)
Light consists of electromagnetic radiations of different frequencies (colors). When light falls on a material, it absorbs certain frequencies. If we see a blue colored object, then it has absorbed all the colors except blue.

2)
Yes.
Light interfere destructively. In Young's double slit experiment, some part of the screen is dark which means that light interfere and cancel out just like sound.

3)
If you shine all the colors in the VIBGYOR spectrum, the table will appear white since white light contains all the colors. You will get different colors for different combination of VIBGYOR colors.

4)
No, some of the light from outside get reflected from the walls and brightens the room. If we paint the wall with light colored paint, it will absorb minimum light and reflect maximum light. So room will be more brighter if we paint it with light coloured paints.

5)
Some objects will not allow light to pass through it, which will cast a shadow behind it. If light is coming from all the directions, there won't be any shadow.
