Electromagnetic waves

What are electromagnetic waves

Transverse waves that transfer energy from the sources of the wave to another absorber

What are properties of electromagnetic waves(3)

They can travel in vacuums, the same speed and all transverse

How do energy and frequency change as you go up the electromagnetic spectrum

energy and frequency gets higher

How does the wavelength change as you go up the electromagnetic spectrum

the wavelength gets shorter

State the order of the electromagnetic spectrum

Radio Waves, Microwaves, infrared rays, visible light, ultraviolet ray, x-rays, gamma rays

How do em waves transfer energy

They can carry energy

How does wavelength affect how much energy is carried by an EM wave

Shorter waves can carry more energy More dangerous

How does energy transfer work in microwaves

Water molecules can absorb some wavelengths of microwaves and the waves can transer to t

How does energy transfer work in infrared rays

All hot objects emit infrared radiation which can be absorbed by other objects

How does energy transfer work from the sun

The sun provides visible light, infrared waves and ultraviolet rays(used for photosynthesis)

What is the relationship between wavelength and frequency

An decrease in wavelength means higher frequency

When will EM waves refract

When they change mediums which changes the speed of the waves
