Light

Question 1

Speed of light in a vacuum?

Answer 1

3.00 x 10^8 m/s

Question 2

What is wavelength?

Answer 2

The distance between Identical points on successive waves.

Question 3

What is amplitude?

Answer 3

The vertical distance between the midline of a wave and either its trough or peak.

Question 4

What does frequency mean

Answer 4

Frequency is the number of waves that pass through a point in 1 second. Measured in Hertz or Hz with one Hz = 1 cycle per second.

Question 5

What are the two components of an electromagnetic wave?

Answer 5

• Electric field component

* Magnetic field component

Question 6

What is the symbol for wavelength?

Answer 6

Lambda (λ)

Question 7

What is the symbol for frequency?

Answer 7

Nu (ν)

Question 8

Speed of light symbol and formula?

Answer 8

Symbol (C)
C= λν
Speed of light = wavelength x frequency

Question 9

What is Planck’s constant?

Answer 9

6.626 x 10^-34 Joules x seconds

Question 10

How would you calculate the energy of a single quanta of light?

Answer 10

E = hν

Planck’s constant (6.626•10^-34J•s) • Frequency (1/s) = E

Question 11

What is electromagnetic radiation?

Answer 11

The emission and transmission of energy in the form of electromagnetic waves.
