Page 2: Electromagnetic Spectrum and Wave Behavior

This section details the electromagnetic spectrum and wave behavior, particularly focusing on diffraction. The content is crucial for understanding btec applied science unit 1 physics notes.

Definition: Diffraction occurs when waves spread out while passing through a gap or traveling around an obstacle.

Highlight: The relationship between gap size and diffraction:

Large gap = Low diffraction levels
Small gap = High diffraction levels
Large wavelength = High diffraction levels

Example: Gamma rays $0.0001nm$ are used to sterilize medical equipment and treat cancer, while radio waves $100m$ are used for broadcasting.

Page 3: Radio Waves and Wave Speed Calculations

This page focuses on radio wave characteristics and introduces fundamental wave speed equations, essential for btec applied science level 3 unit 1 physics past papers.

Definition: Wave Speed = Frequency × Wavelength $m/s$

Highlight: Radio waves with different frequencies serve different purposes:

Low frequencies $3MHz$ : Suitable for hundreds of miles
High frequencies $3-30MHz$ : Effective for international communication

Vocabulary:

Ionosphere: The layer around Earth that reflects certain radio waves
Planck's Constant: Fundamental physical constant used in wave energy calculations

Page 4: Practical Applications and Problem Solving

This final page demonstrates practical applications of wave physics through problem-solving and communication systems, valuable for btec applied science unit 1 physics quizlet preparation.

Example: Problem solving involving X-ray wavelength calculations using frequency of 1.07 × 10¹⁹ Hz

Highlight: Communication system process:

Sound waves conversion to radio waves
Radio wave transmission and detection
Reception and reconversion to sound waves

Definition: Time period calculation: T = 1/f, where f is frequency

Page 1: Fundamental Wave Concepts

This page introduces the core concepts of wave physics, explaining the two main types of waves and their essential properties. Waves are energy transfers caused by disturbances, capable of reflection, refraction, diffraction, and superposition.

Definition: A wave is a transfer of energy from one place to another, caused by a disturbance.

Highlight: There are only two fundamental types of waves: Transfer $Transverse$ Waves and Longitudinal Waves.

Example: Water waves and electromagnetic waves are examples of transverse waves, while sound waves represent longitudinal waves.

Vocabulary:

Wavelength: Distance between consecutive peaks or troughs
Amplitude: Height of wave above the zero line
Frequency: Number of complete waves passing a point per second

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Anna

iOS user

Best app on earth! no words because it’s too good

Thomas R

iOS user

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

Basil

Android user

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

Rohan U

Android user

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

Elisha

iOS user

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
