When will you place an electric lamp from a convex lens so that a parallel beam of light comes out of it?
To produce a parallel beam of light using a convex lens and an electric lamp, you would place the lamp at the focal point of the convex lens. This will cause the light rays emitted by the lamp to become parallel after passing through the lens. Adjust the distance between the lamp and the lens until the light converges at the focal point and then diverges as a parallel beam.
What is the angle if magnetic field not placed perpendicular nor parallel?
If the magnetic field is not placed perpendicular nor parallel to a surface, it forms an angle with the surface. This angle affects the interaction between the magnetic field and the surface material, impacting phenomena like induction or torque. The angle must be considered in calculations involving magnetic fields in such situations.
What kind of lens has a focal point?
A converging lens, such as a convex lens, has a focal point where parallel rays of light converge after passing through the lens. This focal point is where the image of an object placed at infinity will be formed.
What is the nature of the image formed by a convex mirror when an object is placed in front of it?
The image formed by a convex mirror when an object is placed in front of it is virtual, upright, and smaller in size than the object.
What is a focal point in convex lens?
A focal point in a convex lens is the point where parallel rays of light converge after passing through the lens. It is located on the principal axis of the lens at a specific distance from the lens center, known as the focal length. This focal point is where an image is formed when an object is placed at an appropriate distance from the lens.

Should a Voltmeter always be connected in a series with a component?
Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
What is the nature of the image formed by a convex mirror when an object is placed in front of it?
The image formed by a convex mirror when an object is placed in front of it is virtual, upright, and smaller in size than the object.

Where should the fork and knife be placed after a meal?
After a meal, the fork and knife should be placed parallel to each other on the plate, with the fork on the left and the knife on the right, pointing towards the center of the plate.
How do you draw a ray diagram for an object placed in front of a convex lens?
To draw a ray diagram for an object placed in front of a convex lens, first draw the principal axis and the lens. Then, draw three primary rays: one parallel to the principal axis that passes through the focal point on the other side of the lens, one passing through the center of the lens which continues straight, and one passing through the focal point on the same side of the lens which emerges parallel to the principal axis. The point where these three rays intersect will give the image location.
Does a convex mirror make the image upside down?
No, a convex mirror does not produce an upside-down image. Convex mirrors always produce virtual, upright, and diminished images of objects placed in front of them.
What happens when an object is placed closer to a convex lens?
When an object is placed closer to a convex lens, the image that is formed will be farther away from the lens than the object is. This is because the convex lens will refract the light rays in a way that causes them to converge at a point behind the lens, creating a real and magnified image.
Does Other name of convex mirror diverging mirror?
Yes, a convex mirror is also known as a diverging mirror because it diverges light rays that fall on it, causing them to spread out. This type of mirror forms virtual, upright, and smaller images of objects placed in front of it.
What is runway threshold light?
these are the lights that are placed in the areas where the aircraft first touches the runway. the runway threshold ligts should be placed perpendicular to runway center line and as close as possible.The lights should show visible green in the direction of aircraft.
