1.

Explain how electromagnetic waves are alike and how are they different?

a)

Radio waves, microwaves, infrared waves, ultraviolet rays, x - rays, and Gamma rays they are arranged for increasing frequency and decreasing wavelength

b)

Red, orange, yellow, green, blue, and violet are the colors and they are arranged in that way because they are in order for increasing frequency and decreasing wavelength

c)

A microwave to cook food and the lights in my house

d)

They have the same speed, wavelength, and frequency All electromagnetic waves travel at the speed of light as transverse waves in a vacuum. However, they have different wavelengths and frequencies.

2.

Know the order of the visible light spectrum colors and why they are arranged in that manner.

a)

They have the same speed, wavelength, and frequency All electromagnetic waves travel at the speed of light as transverse waves in a vacuum. However, they have different wavelengths and frequencies.

b)

Red, orange, yellow, green, blue, and violet are the colors and they are arranged in that way because they are in order for increasing frequency and decreasing wavelength

c)

Radio waves, microwaves, infrared waves, ultraviolet rays, x - rays, and Gamma rays they are arranged for increasing frequency and decreasing wavelength

3.

What waves make up the electromagnetic spectrum in order and how are they arranged?

a)

Radio waves, microwaves, infrared waves, ultraviolet rays, x - rays, and Gamma rays they are arranged for increasing frequency and decreasing wavelength

b)

Red, orange, yellow, green, blue, and violet are the colors and they are arranged in that way because they are in order for increasing frequency and decreasing wavelength

c)

They have the same speed, wavelength, and frequency All electromagnetic waves travel at the speed of light as transverse waves in a vacuum. However, they have different wavelengths and frequencies.
