What are the possible values of ml for each given value of l=2.

A certain shade of blue has a frequency of 7.25×10^14 Hz. What is the energy ? of exactly one photon of this light? Planck's constant ℎ=6.626×10−34 J⋅s.   ?=______J

The electron microscope has been widely used to obtain highly magnified images of biological and other types of materials. When an electron is accelerated through a particular potential field, it attains a speed of 3.80  106 m/s. The mass of the electron is 9.11 x 10-31 kg. Planck's constant has the value h = 6.63 x 10-34 J-s. What is the characteristic wavelength of this electron?Wavelength =  mIs the wavelength comparable to the size of atoms? No, since atomic radii are on the order of 10-50. No, since atomic radii are on the order of 1-5. Yes, since atomic radii are on the order of 1-5 .

Using Planck's constant as h = 6.63 × 10−34 J⋅s, what is the wavelength of a proton with a speed of 5.00 × 106 m/s? The mass of a proton is 1.66 × 10−27 kg. Remember to identify your data, show your work, and report the answer using the correct number of significant digits and units.

A photon with an energy of 1.01 x 10-16 Joules has what frequency, in Hz?   Express your answer to the correct number of significant figures, in scientific notation and include units with your answer.

measured to have a wavelength of (3.51x10^2) nm. What is the frequency • the correct number of significant figures • written in correct scientific notation Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: -9 8.55 MHz x10 of the light (in Hz)? c = 3.00 x 108 m/s 1 Hz = 1 s 1 Be careful with your units!!! For full credit, your answer must be:

9 of 99 of 9 Questions                                                                                                                                                                                   A wave of blue light has a frequency of 7.65x1014 s-1.  What is the energy of each light wave? Use h = 6.626x10-34 J•s.  Express your answer to three significant figures and in proper scientific notation.

if n=2 what are all of the allowed values of l and ml?
