Answer: A diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.
Explanation:
Electromagnetic spectrum shows the wavelength or frequency ranges of different electromagnetic radiations. According to this spectrum, the range for infra-red region is from .
Therefor, a diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.
Answer:
The speed of a wave is a measure of the product of its frequency and wavelength. ... Since the frequency is kept constant, then it is the constant of proportionality. The wavelength is directly proportional to the speed. Therefore, if speed is increased, wavelength will increase.
