Electromagnetic waves

Question 1

All types of electromagnetic radiation travel at the speed of…

Answer 1

light, 3 x 10⁸ ms‾¹

Question 2

what type of nature do they have and what does it allow

Answer 2

they have a transverse nature so they can interfere, be diffracted and polarized

Question 3

what is the equation that they all obey

Answer 3

v= fλ

Question 4

what do they do with energy

Answer 4

they carry energy from one place to another and can be absorbed by matter to cause heating and other effects

Question 5

What is a wave

Answer 5

A wave is a combination of travelling magnetic and electric fields that vary in value and are at right angles to each other and the direction of propagation of the wave

Question 6

Electromagnetic waves are (highest frequency and lowest wavelength)

Answer 6

Gamma rays
X-rays
Ultraviolet rays
Visible light
Infrared red rays
microwaves
TV waves
radio waves

Question 7

since v=fλ if speed is constant

Answer 7

f and λ would have inverse relationships as f (increasing) λ(decreasing) or as f(decreasing) λ(increasing)
