You have to use your math is this question. First you have to put in all your number in the math equation once you get your value divide that by the diameter of the light bulb to the diameter of the actual object.

What are two uses for a convex lens?
Concave lenses are used in glasses for people who are near-sighted. Convex lenses are used in glasses for people who are far-sighted.
What is it called when a mirror bends inwards or outwards?
Convex when it bends outwards, concave when it bends inwards
How is an image seen in a plane mirror with the image in a convex mirror different?
Concave: a curved like a segment of the interior of a circle or hollow sphere; hollow and curved Convex:having a surface that is curved or rounded outwards plane-a flat mirror
What mirror causes light rays to converge?
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.
What lies inside a flood light?
A convex mirror is present inside flood lights.
How many centimeters is the diameter of the Hubble telescope's mirror?
The primary mirror of the HST has a diameter of 2.4 m; the secondary mirror measures 30 cm in diameter.
Why the study was under taken of focal length of a convex lens by graphical method?
to determine the focal length of a convex mirror.
What is the size of a telescope is expressed in terms of?
The diameter of the biggest lens or mirror that gathers light arriving from space. The diameter can be in mm, inches or metres.
How big is the mirror on the Hubble Teloscope?
The main mirror is 2.4 metres in diameter.
What is the diameter of the Hale telescope at Mount Palomar Observatory?
The objective mirror is 5.1 meters (200 inches) in diameter.
Where would you stand if you wanted to see an upside down reflection of yourself in a convex mirror?
It is not possible to do this with a convex mirror. If the mirror is concave you just have be twice the focal length away from the surface of the mirror or more.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
How is resolution affected by the size of a telescopes mirror or lens?
The resolution is directly proportional to the diameter of the main mirror or lens. For instance, twice the diameter means twice the resolution.
How do you derive relation between focal length and radius of curvature of convex mirror?
the curvature mirror the emage of the mirror is virtual
How is the size of a reflecting telescope indicated?
The diameter of the concave mirror.
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.
What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.
