Here is my question Wave theory and quantum theory appear. Does wave theory apply to electromagnetic waves and quantum theory to particle waves? ●Since electromagnetic waves are light, they are made up of photons.

How many photons strike the screen each second?arrow_forwardAn X-ray machine makes a picture of a broken arm (shown above)by sending high energy photons through an object that is opaque to visible wavelengths and measures the relative intensity of the X-rays that emerge on the other side. Denser substances, such as bone, absorb more photons than less dense substances and thus show up differently. Absorption length 3.4 m Material Air Fat 0.052m Water 0.047m Bone 0.017m Consider the table of X-ray absorptions shown above. Near the center of an arm, the X-rays pass through 2.4 cm of muscle, 3.4 cm of bone, and 3 more cm of muscle. What fraction of the incident X-rays get through this part of the arm? (Hint: assume muscle has the same x-ray stopping power as fat.) Submit Answer Tries 0/99 Assume now that the same beam of X-rays pass through an adjoining portion of the arm (say, directly between the two bones seen), so the path through the arm is the same but the X-rays are only going through muscle and fat.
