Here Comes The Sun's Energy

Sunlight is composed of energy that is visible to humans and energy that is not visible to humans. Which statement describes how the visible energy from the Sun is different from the non-visible energy?

• It travels at a different speed through space.

• It travels a different distance through space

• It has different wavelengths.

• It has different amplitudes.

All electromagnetic waves travel at the same speed in a vacuum. However, different kinds of electromagnetic waves have different wavelengths. For example, microwaves have longer wavelengths than visible light. How is it possible for both microwaves and visible light to travel at the same speed in a vacuum if they have different wavelengths?

• Microwaves and visible light have the same energy.

• Microwaves and visible light have different frequencies.

• The waves of visible light have less energy than microwaves,

• The distance between a point on one wave to the identical point on the next wave is the same for both microwaves and visible light.

True or false: as you move along the spectrum, left to right, the wavelengths decrease in size (get smaller)

• true
• false

A wave with a large wavelength will have a ______ frequency and _____ energy

• high, low
• high, high
• low, high
• low, low

Select the correct order of waves on the EMS 

• Radio, Micro, Infra, Visible, Ultra, X-ray, Gamma
• Gamma, X-ray, Ultra, Vis, Infra, Micro, Radio
• Vis, Micro, Infra, Ultra, X-ray, Gamma, Radio
• Micro, Radio, Vis, Infra, Ultra, X-ray, Gamma

Which has the LONGEST wavelength and, therefore, the lowest frequency/energy

• Gamma Rays
• Radio Waves
• Visible Light
• Infrared rays

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays

Which section of the spectrum is the ONLY one we can see?

• X-rays
• Visible Light
• Gamma Rays
• Ultraviolet Rays

Put the visible light colors in order from longest wavelength to shortest wavelength

• Violet, Indigo, Blue, Green, Orange, Yellow, Red

• Red, Yellow, Green, Orange, Violet, Blue, Indigo

• Red, Orange, Yellow, Green, Blue, Indigo, Violet

Which of the following electromagnetic waves is given off as heat? 

• Radio Waves
• Infrared Rays
• Visible Light
• Gamma Rays
