[Verse 1]
The sunlight bouncing off of me
Reflecting back out to infinity
I’m sending light, all day and night
[Bridge]
Sunshine on my face
Reflecting off the surface
Will they see a trace
Of my race
[Chorus]
I’m sending you a signal
(come one and all)
I’m sending you a sign
(Travel throughout time)
[Instrumental, Harp, Triangle]
[Verse 2]
I’m waving to you
From my point-of-view
Are you waving back
Insight I lack
[Chorus]
I’m sending you a signal
(come one and all)
I’m sending you a sign
(Travel throughout time)
[Bridge]
Sunshine on my face
Reflecting off the surface
Will they see a trace
Of our grace
[Instrumental, Saxophone Solo, Guitar]
[Break]
Wave!
[Verse 3]
So, did you know,
I’m waving hello
Hi.
Or goodbye,
I really don’t know
[Break]
Wave!
[Chorus]
I’m sending you a signal
(come one and all)
I’m sending you a sign
(Travel throughout time)
[Break]
Wave!
[Bridge]
Sunshine on my face
Reflecting off the surface
Will they see a trace
Of our grace
[Outro]
So, wave, Hello
Wave, Good-bye
Hi
[End]
A SCIENCE LESSON
Humans primarily emit electromagnetic waves into deep space. These waves include various forms of electromagnetic radiation, such as radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
- Radio Waves: These are low-frequency electromagnetic waves used for communication and broadcasting. Radio transmissions from Earth have been traveling into space since the early days of radio technology.
- Microwaves: These are higher-frequency electromagnetic waves commonly used in microwave ovens and telecommunications. Some human-made signals, such as satellite communication and radar, also emit microwaves into space.
- Infrared Radiation: Humans and human-made objects emit infrared radiation as heat. Infrared radiation is detected by infrared telescopes and sensors, allowing astronomers to study celestial objects and phenomena.
- Visible Light: Sunlight reflected off Earth’s surface and human-made light sources produce visible light that travels into space. Artificial lights, cities, and human activities on Earth contribute to the visible light emissions.
- Ultraviolet Radiation: While humans do not emit significant amounts of ultraviolet radiation, artificial sources such as UV lamps and industrial processes may emit UV radiation into space.
- X-rays and Gamma Rays: Medical imaging devices, industrial equipment, and scientific instruments produce X-rays and gamma rays. However, these high-energy waves are generally absorbed by Earth’s atmosphere and do not penetrate deep into space.
Overall, the electromagnetic waves emitted by humans into deep space are primarily in the form of radio waves, microwaves, infrared radiation, and visible light. These emissions can be detected and studied by astronomers and scientists using space-based telescopes and instruments.
