Wavelength is the distance between two points on the wave vibrating in same phase .this distance represents the length of of a single wave.
If an object having size comparable to wavelength of a wave comes in the path of the wave then the wave gets polarized around the boundary of obstacle.hence we can say the wave has interacted with the object of comparable dimension.
Hence wavelength roughly represents
Size of object wave can interact with
Size of a single wave cycle
Size of wave.

You will receive partial credit for every correct answer and 1/10 of a point off for every incorrect choice Charged and neutral extended objects do not interact Extended objects of opposite charge can both repel and attract Extended objects of the same charge can both repel and attract Point charges of opposite charge only attract Point charges of the same charge only...

Which of the following statements are true? Note that there may be more than one correct answer; select all that are true. In order for the inference procedures for proportions to be valid, the population from which the random sample is drawn must be normally distributed. As the desired margin of error decreases, then the required minimum sample size will increase. When determining the minimum sample size, if the value of p^ is not given, we should use the "worst-case...

1. Polarimetry can be used to: (more than one answer may be correct) -measure the rotation of plane polarized light, but no further analysis can be carried out using the sample. -separate a pair of optical isomers. -find out which isomer of a chiral product you have made, by comparing the specific rotation to literature values for the same solvent, temperature, and wavelength. -determine the optical purity of the purified product from an enantioselective reaction. -determine the optical purity of...
