1. What is the peak wavelength in the diagram below? 2. How would the wavelength in the image below change if the temperature was changed to 3800?
3. What is the range of wavelengths for the visible spectrum?
4. Use the image below to put the following in order from lowest to highest frequency?
microwaves, x-rays, radiowaves
5. Which of the objects in the image below emits radiation with a wavelength of approximately .01m?

I will mark brainliest to whoever helps me best :)

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
