What two types of microscopes view the surface of an object?
Two types of microscopes that view the surface of an object are stereo microscopes, which provide a three-dimensional view, and scanning electron microscopes (SEM), which provide high-resolution images by scanning the surface with a focused beam of electrons.
What is light bouncing back from the surface of a mirror?
Light bouncing back from the surface of a mirror is called reflection. When light hits a mirror, it is reflected off the smooth surface at the same angle it came in, resulting in an image being formed. Mirrors are used in many applications such as telescopes and microscopes because of their reflective properties.
Which two types of microscopes view the surface of an object?
An optical, and an electron microscope.
What are two things that can reflect light?
mirror and glass
What are the two main types of electronic microscopes?
Biologists use two main types of electron microscopes. Transmission electron microscopes (TEMs) shine a beam of electrons through a thin specimen. Scanning electron microscopes (SEMs) scan a narrow beam of electrons back and forth across the surface of a specimen.
What is plan mirror?
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.

Why is a concave mirror used in microscopes instead of convex lenses?
A concave mirror is used in microscopes because it can magnify the image formed without causing much distortion, resulting in better clarity and resolution. The mirror reflects and converges light rays to focus them effectively, allowing for higher magnification in microscopes. Convex lenses are also used in microscopes to work together with the concave mirror, as they help correct any aberrations in the image and provide additional magnification.
What is the purpose of a two-way mirror and how can you test if a mirror is a two-way mirror?
A two-way mirror is designed to allow one side to be reflective like a regular mirror, while the other side is transparent, allowing people on one side to see through it. To test if a mirror is a two-way mirror, you can place your fingertip on the surface - if there is a gap between your finger and its reflection, it may be a two-way mirror.
How do you find two way mirror?
To determine if a mirror is a two-way mirror, conduct the fingernail test by touching your fingernail to the surface. If there is a gap between your nail and its reflection, it is likely a two-way mirror. Alternatively, shine a bright light on the mirror - if there's a room on the other side, it may be two-way.
What is the number of pole of mirror?
A mirror has an infinite number of poles due to its smooth and continuous reflective surface. The pole of a mirror is the point where the normal to the mirror surface intersects it, and this point can be anywhere on the mirror surface.
