Light And Other Electromagnetic Waves

Question 1

What are the electromagnet waves like?

Answer 1

They are electrical and magnetic disturbances that travel through space and are like light

Question 2

What are the special properties that they can all do

Answer 2

• they all travel at the same speed (300 000 000 m/s) in a vacuum (but slower in other substances)
• they are all transverse waves
• they all reflect
• all travel at the speed of light

Question 3

Just read m8

Answer 3

Like all waves, electromagnetic waves also carry energy, obey the wave equation, travel in straight lines, and can reflect and refract

Question 4

Electromagnetic spectrum order

Answer 4

Radio waves📻, micro-waves🍖, infrared🕶,visible light☀️, ultraviolet🐝, x-rays🦴, gamma rays🦖

Question 5

Which electromagnet has the smallest wavelength?

Answer 5

Gamma rays🦖🐊🦖🐊🦖

Question 6

Most frequency?

Answer 6

Gamma rays

Question 7

What happens when a light meets a new medium?

Answer 7

absorbed
scattered
reflected
transmitted
refracted.

Question 8

On which side of a leslie cube emitts better heat?

Answer 8

matt black surfaces both absorb and emit infrared radiation well, whereas shiny white or silvery surfaces absorb and emit infrared radiation poorly.

So the non shiney black emitts better heat
