1.1 Which of the following sequences properly orders its types of electromagnetic radiation by amount of energy?
The radiated energy levels are increasing from Right to Left
The order is - Radio Waves < Infrared < Visible Light < Ultra Violet < X-Rays < Gamma Rays
Only Option D matches this sequence.
A. Gamma Rays <<Ultraviolet << Visible Light << X-Rays <<Infrared
B. Gamma Rays << X-Rays << Visible Light Infrared << Radio Waves
C. Radio Waves << Infrared << Ultraviolet << Gamma Rays << X-Rays
D. Radio Waves << Infrared << Visible Light << X-Rays << Gamma Rays
1.2 A scientist is conducting an experiment and finds out that the electromagnetic radiation he is using has a wavelength of 573 cm. Can he see the radiation without other special equipment?
573 cm = 5.73 meters
Visible light falls in the wavelength of 380 nm - 740 nm. So the scientist will not be able to see the radiation without any special equipment.
A. Yes, he sees green
B. Yes, he sees yellow
C. No, he cannot
1.3 Which of the following has the greatest wavelength?
Wavelengths of
A. Yellow visible light ~ 600 nm
B. Red visible light ~ 720 nm
C. Infrared radiation ~ 1000 nm
The radiated energy levels are increasing from Right to Left
The order is - Radio Waves < Infrared < Visible Light < Ultra Violet < X-Rays < Gamma Rays
Only Option D matches this sequence.
A. Gamma Rays <<Ultraviolet << Visible Light << X-Rays <<Infrared
B. Gamma Rays << X-Rays << Visible Light Infrared << Radio Waves
C. Radio Waves << Infrared << Ultraviolet << Gamma Rays << X-Rays
D. Radio Waves << Infrared << Visible Light << X-Rays << Gamma Rays
1.2 A scientist is conducting an experiment and finds out that the electromagnetic radiation he is using has a wavelength of 573 cm. Can he see the radiation without other special equipment?
573 cm = 5.73 meters
Visible light falls in the wavelength of 380 nm - 740 nm. So the scientist will not be able to see the radiation without any special equipment.
A. Yes, he sees green
B. Yes, he sees yellow
C. No, he cannot
1.3 Which of the following has the greatest wavelength?
Wavelengths of
A. Yellow visible light ~ 600 nm
B. Red visible light ~ 720 nm
C. Infrared radiation ~ 1000 nm
