2. Arrange the following types of electromagnetic waves in order by wavelength, from longest to shortest: Gamma rays, visible light, infrared radiation, ultraviolet radiation, microwaves, radio
waves, X-rays

Radiowaves >  microwaves> Infrared radiation > visible light > Ultraviolet radiation > x -rays > gamma rays

Explanation:

To solve this problem, we use the electromagnetic spectrum as a reference. On the electromagnetic spectrum, the lesser the wavelength, the higher the frequency and more energetic a wave is.

 Therefore;

  Radiowaves >  microwaves> Infrared radiation > visible light > Ultraviolet radiation > x -rays > gamma rays

So, radiowaves have the longest wavelength and gamma rays have the shortest.

the expression 15n + 2(3p) represents the amount isaiah spent buying gasoline and snacks, where n represents the price of each gallon of gasoline and p represents the cost of each snack that he bought. which statement is true about the amount isaiah spent?
