What is a ray in geometri?
A ray in geometry is a line with a single endpoint and extends indefinitely in one specified direction.
A ray is infinite in one direction.?
true
What is the part of a line that has an end point and runs in one direction?
Ray - A ray is part of a line that has one endpoint. It continues in one direction without ending.
How do you construct the midpoint of a ray?
You cannot. A ray is infinite in one direction and so the midpoint would be infinitely far in that direction.
A can be extended in one direction only?
A ray
A ray of light traveling from air to water will bend which direction?
The ray will bend towards the normal.
What happens to a ray of light as it enters and leaves a glass block?
The ray of light gets refracted. Depending on the medium it is entering, it will bend either to or away from the normal. For example, if it is entering a glass block from air, it will bend towards the normal, and if it leaves a glass block and enters air it will bend away from the normal. The amount the ray bends depends on the angle of incidences and the refractive indices of the two mediums, and are governed by Snell's Law.
When a light ray passes obliquely through the atmosphere in an upward direction how does its path generally change?
Most of the time, a light ray passing through the atmosphere in any direction curves away from its original direction toward the earth's surface. Occasionally, light can proceed straight through the atmosphere with no change in direction. Rarely, it can bend away from the surface.
Does a light ray bend if it enters a glass block perpendicularly?
No, a light ray does not bend if it enters a glass block perpendicularly.
What does a periscope look like?
A periscope looks like a long pipe with a bend on either end. One bend faces a direction, and the other bend faces the opposite direction.
How did Big Bend National Park get its name?
A "bend" is a river is where it makes a significant change in its direction. Big Bend NP is located in an area where the Rio Grande changes its direction from southeast to northeast -- ie, a "big" bend in the river.
Is a ray infinite in only one direction?
A ray is infinite in only one direction.
Why does the light ray bend?
due to the phenomenon of refraction .

Does light bend at the surface or middle of a block of glass?
bend at surface and continued in the same direction in bulk of it...and again bend at emerging surface.........
Would a incident ray bend when it enters a curved plastic container?
Assuming the incident ray enters the container at an angle, yes, but it would also bend if the container was straight. The phenomenon you're asking about is called refraction. The equation describing it is called Snell's Law: sin(θ1)/sin(θ2)=n2/n1 where θ1 and θ2 are the incident and refracted angles of the light ray and n1 and n2 are the first and second medium's "refractive index," which is a number that can be looked up. If the incident ray is perpendicular to the container's surface, θ1 is 0 and there is no bend. The only significance of the container itself being curved is that when the light ray exits the plastic, it may not bend back to the direction it started out with.
What direction has one endpoint and goes on forever?
Honestly a ray does because a ray has one endpoint and it does go in one direction like forever
