Determine whether each statement concerning different wavelengths of light is true or false.
a. the shortest wavelength of uvb light is 280 nm.
b. the longest wavelength of light that our eyes can usually see is 400 nm.
c. light with a wavelength of 100 nm is not visible to the human eye.

Give an example in which the electrical energy changes to light energy

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
