First off, Ultrasound is not a ray. Like all sound, its a wave. Ultrasound simply means its so low in pitch, its below the human hearing range.
When a sound wave hits a barrier, two things happen. The energy from the wave is partially absorbed into the barrier itself, which will now vibrate with that energy. Also, some of the energy from the wave is deflected, or bounced off.
Think of it as being how you can hear someone talk through a wall. Even though the sound waves are bouncing off the wall, and therefore a small room like a closet would amplify the sound, its still being transferred through the wall.
The ray of light reflects.
When a straight light ray hits a smooth mirror, the regular reflection happens.
it reflects
It converges.
Nothing happens when the ray of light hits the pencil. But it bends when it crosses the boundary between the air and the water. Your brain ... thinking that the end of the pencil is in the same direction that the ray of light is coming from ... thinks that the part of the pencil under the water is in a place where it's not, so the pencil appears bent at the water line.
It has the time of its life.
"Normal" means perpendicular to the boundary or reflecting surfaceat the point where the ray hits it.
it will depend on what kind of prisim ( transparent)
The light hits the mirror and the light bounces off like a reflection
It reflect.Reflecting is the bouncing back of light
No, Ultrasound is a specialty and requires more education than an x-ray tech.
The ray bends away from the "normal" a line that runs perpendicular through the boundary of the two materials.
