07 HW What is Light - Electromagnetic Spectrum

All of them are fundamentally the same thing as the light you can see with your eyeballs, they are just of different wavelengths. (or you can say different frequency)

True

God of the sun and air. One of the most powerful and popular gods of ancient Egypt.

Ra

All electromagnetic radiation moves at _.

\n the speed of light

\n

Light is an electromagnetic wave traveling through empty space at a constant speed of  300,000,000 m/s.

\n

True

If wavelength increases energy _.

decreases

All waves move at a speed that is equal to their wavelength times their _.

\n frequency

Figures like Newton and Huygens worked with light in the _ century.

17th century

He was the most important of the gods to the Inca.

The god of the sun.

Inti

If wavelength decreases frequency _.

increases

The different frequencies of electromagnetic waves produce different kinds of light. 

If the light is visible, these frequencies will correspond to different colors.

 Frequencies **greater than** this will exist as _.

UV radiation, x-rays, or gamma rays

The different frequencies of electromagnetic waves produce different kinds of light.

 If the light is visible, these frequencies will correspond to different colors.

Frequencies **less than** this qualify as _.

infrared radiation, microwaves, or radio waves

A more sophisticated description of light which we call classical electromagnetism was developed largely by _ in the 19th century.

\n James Clerk Maxwell

\n

Here we can see all the wavelengths and frequencies ranging from radio waves to gamma rays, and we have found some technological use for all of these in modern society, even though they seem dramatically different, some requiring things like antennas or other equipment to manipulate.

All of them are fundamentally the same thing as the light you can see with your eyeballs, they are just of different wavelengths.

\n

True

If frequency decreases wavelength _.

\

Increases

Electromagnetic waves have amplitudes, wavelengths, and frequencies.

True

If frequency decreases energy _.

\n decreases

\n

The Classical Electromagnetic theory depicts light as a transverse wave composed of oscillating electric and magnetic fields which are at right angles to each other, and _.

perpendicular to the direction that the wave moves

All electromagnetic radiation moves at the speed of light which is about _in a vacuum, the fastest speed possible in the universe.

\n 300 million m/s

The c in this formula represents _.

\n the speed of light

\n

If frequency increases energy_.

increases
