1. compare and contrast microwaves with visible light using wavelength, frequency and energy. (3pts-1pt each for wavelength, frequency and energy)

Arrangement of electromagnetic radiation in increasing order of energy or decreasing order of wavelength is called as electromagnetic spectrum. Electromagnetic radiation is arranged in following order in electromagnetic spectrum:
Radiowaves, Microwaves, Infrared waves, Visible waves, UV rays, X rays

Following are contrasting feature of microwaves and visible ways
1) Wavelength: Microwave (0.1 to 100 cm); Visible rays (400 - 800 nm)
2) Frequency: Microwave (300 GHz – 300 MHz); Visible rays (770 THz – 400 THz)
3) Energy: Microwave (1.24 meV – 1.24 µeV); Visible rays (3.2 eV – 1.7 eV)

Its a hope this
