if your airbag icon is coming on, something is wrong with your airbag system. Have the system checked by a qualified professional. Unless you're within warranty you will probably have to pay for the diagnosis.
To focus the light toward the front.
Adjustment knobs are used to focus light in a light microscope.
Light from stars does not flicker / twinkle, the apparent flickering is due to the distortion of the light from the star as it passes through the Earth's atmosphere.
It could be a problem with the ABS system, but if it just comes on by itself for no apparent reason, it may be the ignition switch.
That is called the star's apparent brightness, or apparent magnitude.
how to replace a front fog light on a ford focus
Yes. The only reason you can see anything is because of light and reflected light. If there is no light, then your eyes don't detect anything. Our eyes work like cameras. When there is little to no light, cameras cannot focus on or "see" anything, just like our eyes.
The abs light stays on when the computer has detected a malfunction and set a trouble code.
to focus light means to condense the energy of a light beam down to a smaller beam through refraction.
Check the door light switches. One could be going bad and triggering the alarm.
Simply put, light rays do not focus light because the focus is on the wrong side of the lens, with respect to the incoming light. If you draw the ray diagram you will see that the parallel rays transmitted may appear to be coming from a focus. This is what they mean by virtual.
A reflective telescope uses concave mirrors to focus light
In watts, or apparent power, in lumens.
Could they possibly be a firefighter? Local volunteer firefighters in Canada have such things in their car.
concave mirror and convex lens can be used to focus light rays. they are also called converging mirror and lens respectively. They focus the light at a distance of its focal length.
Focus punch is in the victory road by the end
tell me the answer
The bending of light rays so they focus on the retina is called refraction.
The exclamation light, on your Ford focus, is a reference to the oil needs to be changed. The light can be reset by changing the oil.
focus [to focus or to gather light] verb. Cause to converge on or toward a central point; "Focus the light on this image"
No, in most media it is less than the speed of light in a vacuum. Some cases have been found where the speed of light in certain media is MORE than the speed of light in a vacuum; but apparently there is reason to believe that this can't be used to transfer information faster than the speed of light; in other words, somehow this is an apparent velocity. Materials with a negative velocity have also been found - the light gets out of the material before it comes in. Again, this seems to be only an apparent speed, not usable for transferring information to the past.
