light optics

What are the two types of oscillating fields produced by electromagnetic waves?

An oscillating electric field and an oscillating magnetic field.

What type of image is formed by a plane mirror?

The image obtained is virtual and laterally inverted.

What is the law of reflection regarding angles?

The angle of incidence is always equal to the angle of reflection for small angles.

What is incandescence?

Light emitted by a substance without combustion or perceptible heat.

What is electrical conduction?

The process of flow of electric charge from one body to another body.

What is triboluminescence?

The emission of light from a substance caused by rubbing, scratching, or similar frictional contact.

Which electromagnetic wave has the lowest energy photons?

Radio waves.

How does light behave when it passes from a less dense medium to a denser medium?

The light will bend towards the normal.

What happens to light at the critical angle?

The angle of incidence where the angle of refraction is 90°.

At what angle do rain and sunlight create a rainbow?

When rain and sunlight mix.

What describes the ability of certain materials to reflect light?

They can behave like mirrors because the light will reflect off them.

What type of lens is described as having a positive focal length and causes parallel rays to converge?

Convex lens.

What is a virtual image?

An image that cannot be projected onto a screen; it appears to be located behind the mirror or lens.

What are the letters that correspond to the types of images formed in a mirror based on reflection?

A i (real), B iv (virtual), C ii (real), D iii (virtual), E v (real).
