If your microscope is a Transmission Microscope then light has to pass through the specimen (that is how the microscope works).
Other kinds of microscopes may not require this.
light passes in straight line
Light passes through many mediums, but some of the most important are: Water Glass Air & Vacuum And light passes through vacuums the fastest.
Light usually passes through a transparent object. Similarly, light passes through the translucent objects but people cannot see through it.
The term for an image through which light passes is a transparent image.
The term for an image through which light passes is a "transparent" image. This refers to an image that allows light to pass through it with minimal distortion.
Yes, if light is diffused as it passes through a material, it is likely to be translucent, meaning that some light can pass through but it is not completely transparent.
When white light passes through a yellow filter, only the yellow wavelengths of light are transmitted while all other wavelengths are absorbed. This causes the light that passes through to appear yellow in color.
Polarised light!
It happens by the refraction of light.
When light changes direction as it passes through a boundary.
Light passes through the cornea, iris, pupil, lens, and finally the retina in the eye.
Through ratina.
