What is electromagnetic waves?The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves, or EM waves. In other words, magnetic and electric fields oscillate to form electromagnetic (EM) waves.
When an electric field interacts with a magnetic field, electromagnetic waves are created. Therefore, they are referred to as "electromagnetic" waves. An electromagnetic wave's electric field and magnetic field are perpendicular to one another (at right angles). Additionally, they are perpendicular to the EM wave's direction. An electromagnetic wave can pass through any medium, including vacuum, solid materials, and air. It can spread or move from one area to another without the use of a medium.

To what temperature will a 50.0 g piece of glass raise if it absorbs 5275 joules of heat and its specific heat capacity is 0.500 J/g°C? The initial temperature of the glass was 20.0 degrees C.
*Include your units!
Round your answer to the nearest whole number.
Answer:
231 C final temperature, 211 C change in temperature
Explanation:
To solve this problem you you use the q=MCΔT equation, where q is heat, m is mass, c is specific heat, and ΔT is change in temperature. Since we're given heat and solving for temperature we rearrange the equation to q/(M*C)=ΔT. At this point we simply plug in the given values to get a ΔT of 211, but this is simply the change in temperature so you add the initial to this to get the final temp.
