Why do astronomical telescopes have big apertures?
they have big apertures because it helps them to observe the sky better. u know wat i mean right?
Why must telescope apertures be larger than the wavelength it is detecting?
To capture the image
Which of the apertures in a clam has an in current flow?
The Ventral aperture has an incurrent flow, the Dorsal aperture has an excurrent flow.
What is the function of apertures?
there is no function of the aperture but there is a function of the shutter. the shutter opens and closes to a certain point, allowing light into the camera. The hole in the shutter is the aperture
What is the advantage of a wide lens diameter?
I presume you really are referring to a large (wide) diameter and not a "wide lens". It will gather more light in a given time, thereby permitting larger apertures for an exposure. Larger apertures will allow faster shutter speeds, which would be useful in sports photography. I don't know your definition of "wide", but I would guess you mean relative to "normal" for a given focal length. Check out what a Canon 200mm F2 or 500mm F4 lens looks like to get an appreciation for a wide diameter.
What part of the microscope help adjust the brightness of an image?
Brightness can be changed by changing the voltage to the lamp and adjusting the condenser and diaphragm/pinhole apertures.
The numerical apertures of the condenser and low power objective lenses are 1.25 and 0.25 you are supplied with a filter that selects a wavelength of 520nm what is the limit of resolution?
346.7nm's
What would someone use apertures for?
An aperture is a hole through which light travels. An aperture can be used for different things including cameras, telescopes and microscopes to name a few.
Are the Nikon Pro Lenses worth the cost and what are the benefits of them?
More expensive lenses usually have more durable construction needed by busy pros and wider / faster apertures (e.g. f:1.4 pro lens maximum aperture vs F:3.5 in consumer lenses). The heavier construction, larger glass elements (needed to let in more light for wider apertures), and fancier coatings add greatly to the cost of professional lenses.
Which part of a light microscope fouceses light onto the spicemen through the lens?
condenser - lens system that aligns and focuses the light from the lamp onto the specimen diaphragms or pinhole apertures
