The transmission axis of the analyzer makes an angle of 53.0 with the axis of the polarizer. (a) What fraction of the original unpolarized light is transmitted through the analyzer? (b) What fraction of the original light is absorbed by the analyzer?arrow_forwardI can analyze electromagnetic waves in terms of color.

- 3. Electromagnetic waves What are the uses of X-rays? Annotate the usesarrow_forwardQuestion 3Radio waves, a type of electromagnetic wave, are emitted by an antenna, picked up by a receiver, and translated into sound waves. Electrons in the antenna oscillate creating the radio waves, and these oscillations are decoded by the receiver to create sound waves in the range of human hearing. This concept is similar to having two aluminum cans connected by a string and sound is transmitted as vibrations in the string.Which statement describes a similarity shared between electromagnetic and mechanical waves?A Electromagnetic and mechanical waves are both transverse waves. B Electromagnetic and mechanical waves are both caused by vibrations. C Electromagnetic and mechanical waves both need a medium to travel through. D Electromagnetic and mechanical waves both travel fastest through high density mediums such as solids.arrow_forward25. Natural light falls on a system of three polarizers with transmission coefficients 0.9, 0.92 and 0.95, respectively, and the transmission planes of these polarizers are angles of 20 °. How will the intensity of light that has passed through all polarizers change if the angle of rotation of the latterpolarizer increase by 10 °, and the angle of rotation of the second - decrease by 10 °?arrow_forward
- If you live in a region that has a particular TV station, you can sometimes pick up some of its audio portion on your FM radio receiver. Explain how this is possible. Does it imply that TV audio is broadcast as FM? Explain why people who have the lens of their eye removed because of cataracts are able to see low-frequency ultraviolet. Why don’t buildings block radio waves as completely as they do visible light? Give an example of energy carried by an electromagnetic wave.arrow_forwardThe main audience for Woodstock 101.9 fm radio is morning commuters heading towards the cities of Brantford and Cambridge along highway 401 and 403. The angle between highway 401 and 403 is 45 ∘ (as shown below). Using 101.9 MHz as the broadcast frequency, the station intends to set two identical antenna at the Woodstock junction in order to maximize the signal along both highways. Part A What minimum antenna spacing should be used by Woodstock radio?arrow_forwardTrue or False; if false, please explain Light (electromagnetic waves) carry energy (Poynting vector) and also carry linear momentum that can be transferred to other objects. The amount of momentum light carries is enormous, which is evident because on TVwhen people get shot by laser-guns they go flying around like weightless rag-dolls and we know that what is on TV is always true.arrow_forward
