positive angles of refraction or diffraction; negative angles of reflection; narrow aberration
You need a lens, an object to view, and a light source to magnify an object. The lens will help in focusing the light and enlarging the object, while the light source will help illuminate the object for better visibility.
Magnifiers must have a lens or system of lenses that can bend and focus light rays, providing an enlarged image of the object. They also need a minimum focal length to enhance the size of the object when viewed through the lens.
As a verb it means to physically place an object next to another object. In common English it refers to postponing a task in order to complete another.
Subject-verb-object is the normal - but by no means the only - order of the main ideas in a simple declarative sentence. "Agreement" is another matter.
An object must have magnetic properties (such as containing iron, nickel, or cobalt) in order to be affected by a magnetic field. This property is known as ferromagnetism, which allows the object to become magnetized and interact with magnetic fields.
A mineral must be naturally occurring, inorganic, solid, have a defined chemical composition, and possess a crystalline structure. These properties distinguish minerals from other substances.

In order for a force to work on an object, there must be an interaction between the object and another object or system that exerts the force. This interaction requires contact or some form of field that allows the force to be transferred. Additionally, the force must have a direction and magnitude to produce a measurable effect on the object.

In order for heat to transfer from one object to another by physical contact, the objects must be at different temperatures. Heat naturally flows from the object with higher temperature to the object with lower temperature until thermal equilibrium is reached.
An object becomes negatively charged by gaining electrons. Electrons are negatively charged particles that can move from one object to another, causing an imbalance of charge and resulting in the object becoming negatively charged.
