Pleasse will give brainlest key questions and terms notes the way that light waves interact with different mediums is called the when does reflection occur? when does refraction occur? when light can pass through an object, it is called when does absorption occur? describe how visible light interacts with these materials: mirror: glass of water: dark fabric: what are some examples of matter waves? what are some examples of electromagnetic waves? how are electromagnetic waves different from matter waves? would outer space be an ideal spot for a concert? why or why not?waves need to interact with particles of either a solid, liquid, or gas to travel. waves do not need to interact with other particles to travel.

It really depends on what you want the most from your concert experience. I've been first and second row at sold out concerts and while the view of the band was amazing, being crushed against the barrier was not. And when there isn't anyone in front of you, it's hard to dance and you don't really get to experience the energy of being in the middle of the crowd. Also earplugs are a must.

Being towards the middle can also be fun and the energy is great. I'm very short so the view isn't that great, but it can be a great experience. However when I've been in the middle I've had several mosh pits start right next to me that I've had to escape from, so beware.

Having seating at a concert  is an entirely different experience from being on the floor. The view is better than the middle of the floor but definitely not as good as being center of the front row. It's definitely nice to be able to sit between sets and have your spot reserved so you don't even have to be hours early. If you don't like getting squished up against drunk and sweaty strangers then seating is perfect for you. The energy of the seating is a little more subdued, but it's still a good experience.
