What else can I help you with?
A gamma ray is a very high speed particle with no charge. True or false?
It is false. A gamma ray has no charge, but it is an electromagnetic wave, not a particle.
True or false virtual images are always inverted?
Just draw a couple of ray diagrams through a positive lens and you will see that a real image has to end up inverted, just like the image in your eye, which your brain then sorts out to a right-way-up image.
How to draw a ray in a geometric figure?
To draw a ray in a geometric figure, start by drawing a straight line. Then, draw a point on one end of the line to represent the starting point of the ray. Finally, draw an arrow on the other end of the line to show the direction the ray extends infinitely.
When you shine a flashlight at a mirror the ray of light that shines back at you is the ray of incidence?
When you shine a flashlight at a mirror, the ray of light that shines back at you is the ray of reflection, not incidence. The ray of incidence is the incoming ray of light that strikes the mirror. The ray of reflection is the outgoing ray that bounces off the mirror at an equal but opposite angle to the incident ray.
Do gamma rays have a higher frequency than x rays?
Generally speaking, it is gamma rays that have a higher frequency (and energy) than X-rays. The upper end of the X-ray spectrum and the lower end of the gamma ray spectrum enjoy a bit of overlap, but the X-ray does not have a higher frequency than the gamma ray.
A ray contains no endpoints?
A ray has no endpoints true or false
A ray has two endpoints true or false?
False.
A ray has an infinite number of endpoints true or false?
false
What is a line that has a beginning but no end?
A ray.
Does a line have a beginning but no end?
No. A geometric line has no beginning or end. A ray has a beginning, but no end. A line segment has both a beginning and an end.
Does a line have a endpoint?
No A line segment has a beginning and an end, but a line has no beginning or end. A ray has a beginning but no end.
A ray extends infinitely in both directions true or false?
False
True or false Assume ray lies inside the angle ADB?
False
Which has beginning point but no end point?
A ray has a beginning but no endpoint.
Is the angle between the incident ray and the plane mirror is the complement of the angle of incidence true or false?
true or false
True or false The endpoint of a ray is always the second of two letters used to name the ray?
False. It could be the first letter.
how are the ray's wings adapted to the marine environment?
True or false
