Step-by-step solution for: Waves - MATH & SCIENCE WARRIOR
To solve the problem and fill in the blanks, we need to use our knowledge of the electromagnetic spectrum and its properties. Let's go through each section step by step:
---
#### X-Rays
- X-rays are used to make ________ of the body.
- X-rays are used to make images (or pictures) of the body.
- X-rays pass easily through ________ tissue, but not as easily through ________ tissue.
- X-rays pass easily through soft tissue (like skin and muscle) but not as easily through dense tissue (like bones).
- All EM waves, regardless of type, travel through ________ (or a ________) at the ________ of ________.
- All EM waves travel through vacuum (or space) at the speed of light, which is approximately \(3 \times 10^8\) meters per second.
#### Visible Light
- Visible light is the ________ that our ________ can see.
- Visible light is the portion of the electromagnetic spectrum that our eyes can see.
- ________ is the longest. ________ is the shortest.
- In visible light, red has the longest wavelength, and violet has the shortest wavelength.
#### Microwaves
- Used in many types of ________ signals such as ________, wi-fi, and ________ and in microwave ________.
- Microwaves are used in many types of communication signals, such as cell phones, wi-fi, and radar, and in microwave ovens.
- EM waves are ________.
- EM waves are transverse waves, meaning their vibrations are perpendicular to the direction of wave propagation.
- The vibrations are at ________ angles to the direction of ________.
- The vibrations are at right angles to the direction of wave propagation.

#### Gamma Rays
- Produced by ________ elements. Cannot be ________, but can cause ________ or ________. Also used to ________ cancer.
- Gamma rays are produced by radioactive elements. They cannot be blocked easily, but they can cause mutations or cancer. They are also used to treat cancer.
#### Ultraviolet (UV)
- Found naturally in ________. Causes ________ and ________. Sunblock products protect against UV ________.
- Ultraviolet rays are found naturally in sunlight. They can cause sunburn and skin damage. Sunblock products protect against UV radiation.
#### Infrared
- Infrared means “________.” As ________ it is used in ________ and ________ used in electronics such as ________.
- Infrared means “below red” (infra = below, red = red). As heat, it is used in toasters and heaters. It is also used in electronics such as remote controls.
#### Radio Waves
- The ________ wavelength in the spectrum. Used to ________ radio and TV ________ around the earth.
- Radio waves have the longest wavelength in the spectrum. They are used to transmit radio and TV signals around the earth.
