Jamal would like to alter the wavelength of a particular beam of light for an experiment. What would he need to change to cause this effect?
change the temperature surrounding the beam
introduce a material for it to pass through
alter the speed the light is traveling
increase the force behind the light beam
To alter the wavelength of a beam of light, Jamal would need to introduce a material for it to pass through. The property of the material through which light travels affects its wavelength. This phenomenon is known as refraction. The wavelength of light changes when it passes from one medium to another with a different refractive index. By selecting an appropriate material, Jamal can cause the light to bend and consequently alter its wavelength.
