Which of these will reflect light with the highest frequency?
an orange basketball
a blue candle
a green ribbon
a yellow banana

The correct answer is an orange basketball.

Explanation:

Frequency is defined as the number of waves that passes a given point per second. It is expressed in Hertz.

White light splits into 7 colors when passed through a medium having different refractive index. The colors are Red, Orange, Yellow, Green, Blue, Indigo and Violet.

The color having highest frequency and lowest wavelength is red.

The color having lowest frequency and highest wavelength is violet.

The order of highest frequency to lowest frequency of the colors follows:

Hence, the correct answer is an orange basketball.

explanation:

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
