Radiowaves

Question 3

If frequency increases what happens to energy and wavelength?

Answer 3

Energy- increases
Wavelength- decreases

Question 4

If wavelength increases what happens to energy and frequency?

Answer 4

Energy-decreases
Frequency- decreases

Question 5

What is quanta?

Answer 5

energy that can only be absorbed or relaesed from atoms in certain amounts

Question 6

how can the energy of electrons jumping from one orbital to another be described?

an analogy

Answer 6

it is a piano not a violin

meaning they have set amounts of energy that is given off not any energy

Question 7

What are photons?

Answer 7

A type of electronmagnetic radiation that can be thought as a stream of very small particles

Question 8

What must be done in energy of photons of light equation?

Answer 8

there must be some sort of conversion into the correct units as speed of light is measured in metres

Question 9

As the concentration of an ion solution increases, there is an increase in what?

Answer 9

intensity of radiation absorbed

Question 10

What increases the intensity of the wavelengths?

Answer 10

increasing the concentration of solution
