Question

note sheet
the electromagnetic spectrum
label the colors of visible light in the correct order.
label the type of em radiation above each image.
wavelength (λ) (measured in meters)
frequency (ν) (measured in 1/seconds or hertz)
energy (e) (measured in joules)
as wavelength decreases, frequency _. thus, wavelength and frequency are _ proportional.

Explanation:

Step1: Recall the order of visible - light colors

The order of visible - light colors from longest to shortest wavelength is red, orange, yellow, green, blue, indigo, violet.

Step2: Identify EM radiation for images

Radio - waves for the radio image; Microwaves for the microwave oven image; Infrared for the remote - control image; Visible light for the light - bulb image; Ultraviolet for the sunburn image; X - rays for the X - ray image; Gamma rays for the radiation symbol image.

Step3: Analyze wavelength trends

As we move from left to right on the electromagnetic spectrum, wavelength decreases.

Step4: Analyze frequency trends

Frequency is inversely proportional to wavelength. So as wavelength decreases, frequency increases.

Step5: Analyze energy trends

Energy is directly proportional to frequency ($E = h
u$, where $h$ is Planck's constant). So as frequency increases, energy increases.

Answer:

• Colors of visible light (from longest to shortest wavelength): red, orange, yellow, green, blue, indigo, violet
• Radio - waves (radio image), Microwaves (microwave oven image), Infrared (remote - control image), Visible light (light - bulb image), Ultraviolet (sunburn image), X - rays (X - ray image), Gamma rays (radiation symbol image)
• Wavelength: Decreases from left to right
• Frequency: Increases from left to right
• Energy: Increases from left to right
• As wavelength decreases, frequency increases. Thus, wavelength and frequency are inversely proportional.
