Summarize what you learned this week about the electromagnetic spectrum HINT: What is it? What does it organize? How do we use these EM waves in our lives?

Electromagnetic spectrum consists of
Radio waves
Microwaves
Infrared
Visible light
Ultraviolet
X-ray
Gamma ray

We use these everyday in our life however they also have dangers.

Radio waves - their long wavelength allows them to help with communication
Danger - exposure to a lot of radio waves can cause cancer or leukaemia

Microwaves - used for heating up food and transferring heat to the food.
Dangers - exposure can cause cancers and other diseases.

Infrared - can be used for remote controls and security cameras.
Danger - can cause damage to the cornea in your eye

Visible light - used for photography and optical fibres.
Danger - intense sources can cause permanent or temporary damage to the eyesight.

Ultraviolet - can be used to sterilise food and sterilise surgical equipment.
Danger - can cause skin damage and may lead to a cancer.

X-rays - used to see the internal structure of tissues and bones.
Dangers - can lead to mutations and May damage the cells

Gamma- can be used to sterilise food and surgical equipment and kill microorganisms and other bacteria.
Dangers - May reach your cells and cause cancer and cell mutations which could result in mutations.

Nps pollution is caused by rainfall or snowmelt moving over and through the ground. nonpoint source pollution can include: excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. oil, grease and toxic chemicals from urban runoff and energy production

Answer

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

explanation

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
