How does a radio telescope see objects which are too dim for an ordinary telescope?
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
What else can I help you with?
What is the single most important component of a telecope?
It is the main light-gathering component, the main mirror of a reflector or the object-lens for a refractor. That determines the power of the telescope to gather light from dim objects and provide a clear image.
Why does car lights dim and radio shuts off?
Flat battery !
What happens to shadows in dim light?
Shadows become less defined and lighter in dim light because there is less contrast between the light and darkness. In dim light, objects may cast fainter and softer shadows.
Why is stargazing more difficult when the full moon is in the night sky?
The bright sunlight reflected from the Moon will wash out the sky and make it more difficult to observe dim objects. If you have a good telescope, then it's not too bad, as long as you're not trying to observe things that appear to be close to the Moon.
Why do objects tend to look black and white in dim light?
Because the cells in the retina of your eye that produce the sensation of color are insensitive to dim light, and images in dim light are perceived by other retinal cells that are less interested in color.
Why would your car radio dim your dash lights?
because it is using up lots of power :)
Does your 2004 Chevy Impala's odometer and radio dim when you turn on the headlights?
Yes. Far as I know all cars do. They dim for night driving and may not be readable in the day time.
4 uses of a variable resistor?
dim lights, tune in a radio on an analog radio, control heating elements in an electric stove, volume controls.
Can you see Ceres at night with out a telescope?
No, except in rare optimal viewing conditions. Its brightest magnitude is 6.7, which is normally too dim for the unaided eye.
Why do the dash radio and clock light dim when the head lights are turned on?
The headlights place a larger load on the battery and cause the voltage to drop enough to dim other devices slightly.
Which is an example of visual basic objects?
dim a as integer dim b as integer dim c as integer dim d as integer private sub command1_click () a=-1 b=1 d=1 while (d<=10) c=a+b print c a=b b=c next d end sub
Can you see Ceres from earth?
With a telescope, yes. You can't see it without a telescope though.
