Key Concepts

Electromagnetic Spectrum

The electromagnetic spectrum represents the range of all types of electromagnetic radiation, arranged according to their wavelength, frequency, or energy. Understanding this spectrum helps us classify different radiations such as radio waves, microwaves, infrared, visible light, ultraviolet, and X-rays, based on their physical properties and interactions with matter.

Relationship between Wavelength, Frequency, and Energy

Wavelength, frequency, and energy of electromagnetic waves are interconnected. A longer wavelength implies a lower frequency and lower energy, while a shorter wavelength corresponds to a higher frequency and higher energy. These inverse relationships are fundamental in determining how different types of electromagnetic waves behave and interact with various substances.

Spectral Regions and Their Order

The various regions of the electromagnetic spectrum can be ordered by increasing wavelength, frequency, or energy. This ordering is crucial for applications in communication, medical imaging, astronomy, and other scientific fields, as it determines the penetration power, resolution, and overall suitability of each type of radiation for specific tasks.

00:01 Hi, everyone.

00:01 I'm here with problem to from chapter seven.

00:05 So in this problem were given different types of radiation and were asked to order them in increasing frequency, wavelength and energy.

00:17 So first, we're going to go through our types of radiation.

00:20 So we're given microwave ultraviolet radio waves, infrared, x trait and visible.

00:29 And here i have listed there, frequency manger's in hurts.

00:39 Then we can use this to help us order.

00:45 But first, let's go over how energy, frequency and wavelength are all connected.

00:51 So we know through the equation, e is equal to plank's constant age.

01:01 Times the frequency.

01:04 Yeah, new gives us energy.

01:07 But we can also relate this to wavelength as he speed of light, divided by the wavelength, times things constant.

01:23 And we can get this through our relationship of the speed of light to the frequency and wavelength which is c is equal to frequency times wavelength.

01:41 So we can see that has energy increases.

01:51 We know our frequency also increases so there, directly proportional to each other.

01:59 We also know that as he increases the wave length decreases and so they're inversely proportional.

02:14 So now we can go through ordering so let's start with increasing frequency.

02:20 So if we use our list, let's find the lowest frequency.

02:29 So, out of all of these, our lowest frequency is going to be radio waves.

02:40 Let's go from 10 to the fourth to tend to the night...
