Thank you for your help in advance... I have attached a picture of the graphs
do u have all the answers?
If you want to check your answers, @Morgan is right for Connexus. (P.S, it's in another answer link...)

16. The electromagnetic wave shown above is made of vibrating
A. It's vibrating in different ways, like having a dance party of transverse and longitudinal waves!
17. In the diagram above three beams of light encounter a medium. How can the medium be described?
B. It's like a curtain that can't fully hide the light, so we can say it's translucent!
18. Why did the bicycle fall over?
Because it was two-tired!
19. The light ray is entering the water from the air. How should the light ray respond to the change of medium?
B. It's like the light ray found a water slide that speeds it up and bends it downward!
Hope that brings a smile to your face! Let me know if you have any more questions.
To answer these questions, we need to analyze the information provided in the question and use our knowledge of the topic. Let's go through them one by one:
4. The question asks which conditions are best for a sound wave to travel. Unfortunately, you mentioned that there is an image attached, but as an AI text-based bot, I don't have the capability to see or analyze images. However, I can explain what conditions are generally needed for sound waves to travel. Sound waves require a medium to travel through, such as air, water, or solids. They cannot travel through a vacuum or empty space. So, based on this information, you can determine which option shows the best conditions for a sound wave to travel.
12. The question asks which letter represents a type of wave that can be seen by the human eye. Again, I don't have access to the image you mentioned, but I can provide an explanation. The human eye is sensitive to a type of electromagnetic wave called visible light. Visible light occupies a specific range in the electromagnetic spectrum. So, you need to identify which option corresponds to visible light.
15. The question asks what object A does when it acts as a transmitter. To answer this, you need to understand what a transmitter does. In the context of radio signals, a transmitter is a device that sends out radio signals. So, you need to determine which option corresponds to transmitting radio signals.
16. The question asks about the composition of the electromagnetic wave shown. Again, without access to the image, I cannot provide a specific answer. However, I can explain what electromagnetic waves are made of. Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space. They do not require a medium to travel. So, you need to identify which option describes the components of an electromagnetic wave.
17. The question asks how to describe the medium that three beams of light encounter. Based on the information provided, light ray A is reflected, while light rays B and C are absorbed. This suggests that the medium allows some light to pass through but scatters it in different directions, preventing clear transmission. Based on this information, you need to determine the appropriate description of the medium.
19. The question asks how a light ray entering water from air should respond to the change of medium. When light travels from one medium to another, it can either speed up or slow down, depending on the properties of the mediums involved. It can also change direction, or bend, due to the change in the refractive index. With this information, you need to determine how the light ray should respond to the change from air to water.
I hope this explanation helps you understand the thought process and reasoning behind finding the answers to these questions.
