What does the 10 stand for in a 10x32 binoculars?
In the case quoted, 10 is the magnification factor of the binoculars. In other words, objects appear to be 10 times closer viewed through the binoculars compared to with the naked eye.
The type of mirror that resembles the inner surface of a spoon is called?
A mirror that bows inward is called concave. The opposite, a mirror that bows outward would be called convex. Convex mirrors are used to to increase the field of view around corners and blind spots. Concave mirror serve no purpose other than novelty (making you appear thin or odd)
Sunspots are what compared to the gases around them on the sun?
Sunspots appear darker because they are "cooler" than the surrounding area.
How did the sun appear through a telescope?
It would blind you to look at it.
When looking through a telescope what color does mars appear to be?
A tanish color
Compared to its actual size how will an object seen through a convex lens appear?
LARGER!!
An object is placed 4 cm in front of a concave mirror with a focal point of 1 cm describe the image that is formed?
A concave lens will appear!
Write magnification relation in terms of you and v for convex lens and concave mirror?
Convex is () and makes objects appear larger. Concave is )( and makes objects appear smaller. The side rear-view mirrors on cars have concave mirrors, hence, "Object are closer than they appear." Easy way to remember is that a cave is like a hole in the ground, so something is concave if it gets smaller towards the center.
What is a make up mirror Concave or Convex?
I remember this answer by remembering the word 'cave' as in 'concave'. The answer is Concave.
How would the eye perceive an image created by a concave mirror and by a convex mirror?
A concave mirror will focus an image and make it appear smaller. A convex mirror will disperse an image and make it appear larger.
How does concave graph look like?
Many graphs that appear concave from one side will appear convex from the other. A smooth graph is generally described as concave if it is increasing AND if the rate of increase is also increasing. In terms of calculus this requires the first and second derivative to be positive. A concave polygon is one in which at least one of the vertices forms a reflex angle.
What is concave len explain in detail?
In case of concave lens the edges will be thicker compared to the central part. Whereas the convex lens has edges so thin compared to the central part. Concave lens would have only divergence effect. Parallel beam of light falling on one side of the concave lens after refraction would come out from the other side diverging out and so they appear to come from a point on the incident side of lens. So no real image is obtained. Thus the image will be a virtual image. If converging rays fall on the concave lens after refraction may be still converging but it convergence will be reduced a little bit and so instead forming a real image nearby the concave lens it will be formed somehow far away from the lens.
Does a concave lens bend light to make the objects appear larger?
yes it does
Does concave mirrors make object appear bigger?
Yes they do :) Were learning about them in science .
Why some images on mirror appear to be erect?
Some images on a mirror usually appear erect because of the concave mirror.
Which light rays striking a concave mirror are reflected so that they pass through the focal point?
The tendency in case of concave lens would be diverging one. When parallel rays fall one side of the concave lens then due to divergence they appear to come, note down that "they appear to come" from a point on the same side. And this point is named as the virtual focus of the concave lens. Now as a ray passes through this virtual focal point that will be definitely a diverging one. Now due to diverging action of the lens, that ray will be further diverged and that will appear to come from a virtual point on the same side and some what nearer to the concave lens. Hence the image will be virtual and diminished and erect one.
Is magnifying lens a convex or a concave lens?
A magnifying lens is convex i.e. it bulges outwards. A concave lens would make objects appear smaller.
