Question

In the paragraph below, indicate the relationship by entering one of the words larger, smaller, higher, lower, or the same.

You are provided with three light sources: a tungsten lamp, a Nd-YAG laser (output at 1064 nm), and a blue LED. One limit of the tungsten lamp's output is in the UV region, which is _______ in energy compared to the Nd-YAG line. The median output of the tungsten lamp is in the near-IR region, which will be ______ in wavelength relative to the Nd-YAG source. The photons emitted from the blue LED will be _______ in energy compared with those emitted by the Nd-YAG laser and _______ in frequency compared to the near-IR emission from the tungsten lamp.

please explain how you determined your answers.

Explanation / Answer

1. Higher (1064 nm is in Infrared region, which is of lower energy than UV or visible light due to the relation E=hc/(wavelength) ) h= planck's constant , c= speed of light in vacuum

2. the Same Near IR is 800-2500 nm which is in range of 1064 nm

3, Higher (Blue Wavelength @ 400nm , which, according to the relation above, will quote for a higher energy than 1064 nm source )

4. Higher - the relATION can also be written as Energy (E) = h * frequency (v) . Hence Frequency is c/(wavelength) Therefore Blue light, having a shorter wavelength will have a higher frequency and energy.
