Electromagnetic

Question 1

Electromagnetic Waves

Answer 1

Have same speed, c, but cuz they widely have differing wavelengths, frequencies and photo energies you detect use them differently

Question 2

Intensity Equation

Answer 2

I = k/r²

k is intensity 1m from centre of source

r is radius from source

Question 3

Dish Antennas

Answer 3

Sat communication use dish antennas that concentrate wave into a directional beam with flat plane wave-front. So there waves lose intensity more slowly

Question 4

Visible light wavelengths

Answer 4

Has many different wave lengths from deep red (λ=740nm) to indigo blue (λ=370nm)

Question 5

Electromagnetic Spectrum

Answer 5

In reverse order:
Rabbits-Radio

Mate-Microwave

In-Infrared

Very-Visible Light

Unknown-Ultra Violet

Expensive-X-Ray

Gardens-Gamma Ray
