Lab 2 Light and Matter question 1 answers

this is an electromagnetic field and waves lesson question. Please only give the correct answer. (for example correct answer is A,B ..etx)

Course Code: ELEC3252 Course Name: Electromagnetics 2 Spring 2020 Q7. All electromagnetic waves travel through a vacuum at (a) The same speed (b) Speeds that are inversely proportional to their frequency (c) Speeds that are proportional to their frequency (d) (d) None of the choices Q8. Electromagnetic waves are (a) longitudinal (b) both longitudinal and transverse (c) transverse (d) none of the choices Q9. The frequency of an electromagnetic wave in free space with a wavelength 2.75 x 10m (a) 1.1 Hz (b) 1.09 x 10 Hz (c) 9.17 x 105 Hz (d) 9.1 x 10 Hz Q10. Electromagnetic w es travel faster in conductors than in dielectrics. (a) True (b) False

I've seen this is the formula to calculate the wave frequency in free space. But where is this from?

Question 2 View the chart on the characteristics of electromagnetic and mechanical waves and answer the quesi Electromagnetic Waves Mechanical Waves Transverse Waves Transverse, Longitudinal, and Surface Waves Do not require a medium Require a medium Begin with the movement of charged particles Begin when matter is disturbed How is the transfer of energy different in electromagnetic waves compared to mechanical waves? Electromagnetic waves requires a source of energy a Electromagnetic waves can transfer energy through a vacuum, or empty space Electromagnetic waves can change speed or direction Question 3 Select the best answer from the choices below. Light has many properties of waves, but sometimes it also be 04 Polarized light Ultraviolet caa

A property of electromagnetic waves that makes them different than other kinds of waves such as sound or water waves is that Select one: a. their speed can change when moving in different media. b. they can carry power.
 c. they have many possible wavelengths. d. they do not require a medium.

How electromagnetic waves help facilitate innovations in telecommunications,etc...

1. (a) Write down major differences between general wave (i.e. sound wave) and EM wave. Explain the propagation of an EM wave with proper figure. (b) We know that: Maxwell's 4th law [known as Ampere's law] has a quantity: electric conducting current. Now, explain: why there is no magnetic conducting current in the 3rd law of Maxwell's Electromagnetic equation, known as Faraday's law.
