Emerging Technologies



EMERGING TECHNOLOGIES In class/Homework taskWhat are electromagnetic waves (also known as electromagnetic radiation, or EMR)? [2 marks]Why are they called “electromagnetic”? [1 mark]In what single main way does EMR differ from “mechanical” waves? [1 mark]Refer to the attached Wavestown sheet. What is the electromagnetic spectrum (“EMS”)? [1 mark] Using the descriptions on the next page to correctly label the EMS diagram on the Wavestown sheet.[3.5 marks] How does the wavelength and frequency of EMR relate to the EMR’s energy? [2 marks] From the picture, find an object that uses each type of EMR. [3.5 marks]Select One objects from the Wavestown picture that rely on using EMR.For the object answer the following on the table attached:From the spectrum, on what type of EMR is does the object rely? [ 1 mark]Give a brief description of how the object uses EMR to perform its function. [ 3 marks]What are the advantages of the object’s technology?[ 2marks]What are the disadvantages of the object’s technology?[ 2 marks]From the knowledge gained in iii and iv, what is your informed opinion on the use of the object? [ 2marks]Note that for iii and iv you must state the sources of your information and comment on its reliability.In class share your finds with 2- 3 peers and complete the summary table for the other forms of EMR[ 10 marks] Prepare a timeline of the technological development of one of the objects you have discussed above. A minimum of 4 stages in the timeline is required. [ 4 marks]You should describe: how previous technologies worked to perform a similar function [ 2marks ] how changes to the technology improved its performance, and [ 2 marks] how the object may operate in 100 years from now. [ 2 marks ][1 mark per timeline stage + 2 marks per dot point = 10 marks]ObjectType of SpectrumDescriptionAdvantagesDisadvantagesSource of informationlefttopright698500-262719-566382479377632276963173105179325 ................
