What else can I help you with?
Are images sometimes larger than the actual object in a diverging mirror?
no, the image formed is always smaller in magnitude compared to the actual object. i.e. either a diminished point size image is formed at the principal focus or a diminished image is formed.
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror?
When a small object is placed on the principal axis of a concave mirror between the focus and the mirror, a virtual and upright image is formed behind the mirror. The image is magnified and located further away from the mirror than the object.
What are the properties of an image focus on the film in a camera?
The image is inverted and smaller than the object.
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
How does a converging lens bring an object inside its focal point into focus?
A converging lens brings an object inside its focal point into focus by refracting light rays that are parallel to the lens axis. These light rays converge at the focal point, creating a clear and focused image of the object.
What is refractors?
A refractor is a telescope whose principal focusing element is a lens and collects lots of light from a distant object and brings that light, or image, to a point or focus.
What is distance of principal focus from optical centre called?
The distance of the principal focus from the optical center is called the focal length.
Define principal focus and principal aris?
principal focus is the ray which diverge at a point on the other side of the lensPrincipal Axis lens have two centre of culvature,the line passing through them and joining these centres is called principal axis.
What is meant by focus of a concave mirror?
The focus of a concave mirror is the point where parallel rays of light converge after reflecting off the mirror. It is located along the principal axis, halfway between the vertex and the center of curvature of the mirror. Rays of light that are parallel to the principal axis will reflect and converge at the focus.
What should you do first to bring the object in focus on a microscope?
To bring an object into focus on a microscope, you should start by placing the specimen on the stage and selecting the lowest magnification lens. Next, use the coarse focus knob to move the microscope stage upward until the object is visible, then use the fine focus knob to sharpen the image.
When viewing an object through the high-power objective of a microscope not all of the objeect may be in focus why?
The high-power objective has a shorter focal length and a narrower depth of field, making it more challenging to keep the entire object in focus. This is due to the higher magnification, which increases the blur caused by slight differences in the object's distance from the objective lens. Adjusting the fine focus can help bring different parts of the object into focus by compensating for these variations in distance.
What are the characteristics of images formed when an object is placed between F and P using a concave mirror?
When an object is placed between the focal point (F) and the principal focus (P) of a concave mirror, the image formed is virtual, upright, and magnified. The image is located on the same side as the object and is larger than the object itself.
