6. Three vectors are: a = -9]
Work out the following:
a) a +b b) a + c c) b-c d) a - Ċ e) a + b + c
What does the answer to part e) mean?

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation
