Olexes sound flash cards

a membrane in the cochlea that is in the organ of Corti.

a system for the detection of objects under water and for measuring the water’s depth by emitting sound pulses and detecting or measuring their return after being reflected.

a tiny particle of light or electromagnetic radiation

intensity is the power transferred per unit area, where the area is an imagined surface that is perpendicular to the direction of the energy.

an electronic system used to detect,range and velocity

An imaginary line that follows behind in the direction that light travels.

Not the real image you see. It is an apparent path of light rays.

Opposite of virtual image rays are gathered into a single point or small area.

Where random light is reflected off into many random directions, such as a disco ball.

Where light starts to perform like a ray.

The way the ought reflects off a smooth surface

The way a light Ray strikes a surface

That the laws of reflection and incidence are the same angles

Where light hits an object

Mirrors that cave outwards

Mirrors that cave in

complete reflection of a ray of light within a medium such as water surrounding the back into the medium.

Focuses all light into one hole.

Duplicating wavelengths to make objects appear larger.

Used to disperse light

Where light is not appeared the way it really is

Sound waves are when an object is vibrating free air around it making noise

The pitch is affected by what the size of a vibrating object is the larger it is the lower the pitch the smaller it is the higher the pitch

You can hear all infrasound
