Topic 5 - Light And The Electromagnetic Spectrum - Danger Of Em Spectrum

Question 1

What is the effect of higher frequency EM waves on cells?

Answer 1

Higher frequency EM waves transfer too much energy to cells, causing them to mutate and potentially damage them, which can lead to cancer

This is due to the increased energy associated with higher frequency electromagnetic radiation.

Question 2

What type of EM wave is associated with internal heating of body cells?

Answer 2

Microwaves

Microwaves can cause water molecules in body cells to heat up, leading to internal heating.

Question 3

What is a potential effect of Infra-Red radiation?

Answer 3

Skin burns

Infra-Red radiation can cause thermal damage to the skin.

Question 4

What type of damage can UV radiation cause?

Answer 4

Damage to surface cells and eyes, leading to skin cancer

UV radiation is known for its harmful effects on skin and eye health.

Question 5

What are the potential risks associated with X-ray and Gamma radiation?

Answer 5

Mutation or damage to cells in the body

X-ray and Gamma radiation are highly penetrating and can cause significant cellular damage.
