Rockets,Space crafts,and wavelengths.(need help)?

Question

1.Think about what the rocket does in a space craft what is their main purpose within the realm of space exploration?

2.Electromagnetic radiation, such as light, occurs in different wavelengths. The wavelength of the electromagnetic radiation (ER) is related to the energy of the ER Explore the interactive spectrum. Look at the wavelength of each type of ER and determine the relationship between wavelength and amount of energy.

The ____ the wavelengths; the ____ the amount of energy.

Answer 1

The rocket lifts the spacecraft into space so the spacecraft can perform its designed function.

smaller...greater ie. gamma...high energy

larger...low energy ie. radio...low energy (if not cell phones would fry your brain)

Answer 2

1. They are flying through space very fast and they do stuff like land on planets like Jupiter and Mars and they are like totally fast. My friend can run faster than a rocket ship though, but that's not the point, he has Nike's.

2. I play basketball too.

Answer 3

1. Rockets are vehicles to lift their pay load (space craft is a general common-man's term) into orbit around or beyond into deeper space. They provide the thrust required to give the escape velocity.

2, EM (Electromagnetic) waves (also called EM radiation) is a spectral continuum. The waves (or rays) travel at a speed of 300,000 km/sec in vacuum. Its speed gets reduced in material media. EM waves are specified by wavelengths. It can also be specified as frequency; the unit is called Hertz that has the dimension of inverse time (s^-1). Hertz was a Germen scientist who  first one launched these waves into air. When wavelength (the spatial extent of one cycle of wave) is multiplied with frequency (number of cycles per second) gives speed (300,000 km /sec) as it should. Einstein in his photoelectric theory proved that  enrgy of a photon (the basic unit of light or EM energy) is proportional to its frequency. Proportionality constant is 'h', the Planck's constant, named after another German scientist to whom the 'Quantum' concept is owed [h = 6.6262 X 10^-34 J/sec]. Common practice is to express EM wave at higher end, in terms of its energy.

We digress a bit here. 1 volt is the energy per unit 1Coulomb charge. If instead 1electron is raised through a potential of 1volt the energy used is called 1eV(electron Volt). Electron charge is1.6 X 10^-19 Coulomb. 1Coulomb is actually 1/1.6X10^-19 = 6,241,449,210,000,000,000 +/-

70,000,000,000 electrons. If 'f' is frequency of EM wave, its

Energy = hf

but expressed in eV modifying

h = 4.1357 X 10^-15 eV/sec (or eV Hz).

Visible part of spectrum occupies a width (or window)

0.4 to 0.7 |u wavelength ;  {1 |u = 10^-6 meter}

750 to 420 THz frequency;  {1THz = 10^12 Hz}

3 to 1.7 eV energy.

The shorter the wavelength ; the higher the amount of energy.

i dont know sorry for not answering i nedded points...
