Hello everyone! I hope everyone is going well and keeping healthy in what continues to be crazy times! Hopefully everything returns back to normal in the next few weeks! Last week, we discussed how we can get prepared for our revision and also discussed the most effective ways to tackle the topic of light, specifically looking at Young’s Double Slit experiment. If you missed out on the post, definitely go back and have a look! If you have been keeping up with the posts, I would still recommend going back and having a quick skim through the first few posts to pick up any information that you missed on your first reading! Hopefully you can find a golden piece of advice somewhere in the post that you can apply to your study this week! Speaking of which, let’s have a look at what is in store this week!
What are we up to this week?
This week is a great week to start working through some questions with a specific focus on the exam! I know the exam may seem quite a while away but getting started with questions right now will hopefully relieve some of the pressure when revision gets a bit more hectic later on. Last week, we discussed how we should get organised with our resources and revision material and as such the process for this week becomes a lot easier.
From my experience, completing questions from topics that you are not as comfortable with is the best way to get started. Targeting your weaknesses early will allow you to adequately work through any problems that you have; the earlier you quash your weaknesses the better! In terms of the types of questions you do, I would recommend doing questions from a variety of sources. I found this to be the best way to ensure that I was equipped for any question thrown at me in the exam! For areas that you are not as comfortable in, I would recommend starting with your textbooks. Textbooks tend to have more direct questions that can help you understand the concepts a lot better. Mixing in a past exam question or two as you go along will definitely not hurt!
Getting through questions this week will definitely boost your revision progress and you will be well on the way to smashing the final exam! There is not long to go, so getting to work now will make your life a lot easier in the coming weeks!
How can I best understand the wave and particle models for light?
Last week, we discussed how to break down light, specifically in looking at the properties of light as well as Young’s double slit experiment. This week we will take a look at how we can understand the Photoelectric effect and analyse its comparison with Young’s double slit experiment.
On just about every exam that has been made for Physics (involving this topic), a question asking you to compare the wave and particle models of light has been present. This is one of the areas where you almost know going into the exam that a question is going to appear, so it is one that I think is worth preparing for properly.
As you have probably discussed in class, Young’s double slit experiment supports the wave model of light, whereas, the Photoelectric effect supports the particle model. With there being a direct discrepancy, I found the best way to compare the two experiments was through a few tables. The first table I created was simply comparing light against particles. Listing down the properties of waves in comparison to the properties of particles is a great way to understand the fundamental differences between the two theories. The second table I prepared was one comparing the results of the two experiments side by side. This was more so to ensure that I was aware of all of the significant results. After preparing these tables what I did (and what I recommend you do) is draw out two diagrams like this:
I haven’t spoiled the fun by filling in the descriptions for the diagrams, but I think this structure allows you to really break down the two experiments. It is also a great structure to follow when writing out written responses to questions and I found that it made understanding the models of light a lot easier. Of course, I would highly recommend using variations of your own and coming up with your own unique diagrams! Visually breaking down the topic is a fantastic way to tackle this topic and one that I think will hold you in good stead! Once you have your diagrams done, this topic will be a piece of cake!
What mindset should I have for Physics this week?
This week, I think a great mindset to adopt for Physics is one of creativity. So far, we have been pretty straight forward with the approaches we have discussed, so I think this week is a great week to get creative. Be creative in the way you tackle revision questions and be creative with how you revise certain concepts (such as through using diagrams) as this will not only help your learning but hopefully make the process more enjoyable!
Weekly Tips and Tricks
That is all from me for another week! I hope that physics questions treat you well throughout the week and that diagrams help you understand the models of light! Here are three parting tips and tricks to help you get through the week:
1. Watch a YouTube video explaining the models of light
A visual representation of information can sometimes be helpful in your understanding!
2. Track your questions!
Note down the questions you do and what topics you are covering! This will be helpful later one when you are not sure what to revise!
3. Have plenty of breaks (same as last week)!
With everything that is going on, it is very important to ensure that your health and wellbeing is flourishing! Make sure to take plenty of breaks and have some fun in between attending classes and studying.
