PASSAGE: Wavelength: 266 and 325 Power (mW): 1.5 and 2.2 Pulse duration (ms): 5 and 2 Which laser is suitable for the MALDI technique after its frequency is doubled? A. Laser A: wavelength 826 nm, power 1.2 mW B. Laser B: wavelength 714 nm, power 1.2 mW C. Laser C: wavelength 650 nm, power 1.5 mW D. Laser D: wavelength 532 nm, power 1.5 mW correct answers The answer to this question is D because the wavelength must be either 266 nm or 325 nm, and by doubling the frequency of the laser...

Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...
