Since 1\u2009MHz=1\u00d7106\u2009Hz1 \\, \\text{MHz} = 1 \\times 10^6 \\, \\text{Hz}1MHz=1\u00d7106Hz, we can convert the frequency: f=91.5\u2009MHz=91.5\u00d7106\u2009Hz=9.15\u00d7107\u2009Hzf = 91.5 \\, \\text{MHz} = 91.5 \\times 10^6 \\, \\text{Hz} = 9.15 \\times 10^7 \\, \\text{Hz}f=91.5MHz=91.5\u00d7106Hz=9.15\u00d7107Hz<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Calculate the wavelength<\/h3>\n\n\n\n<p>Now, we can plug the values into the formula for wavelength: \u03bb=3.00\u00d7108\u2009m\/s9.15\u00d7107\u2009Hz\\lambda = \\frac{3.00 \\times 10^8 \\, \\text{m\/s}}{9.15 \\times 10^7 \\, \\text{Hz}}\u03bb=9.15\u00d7107Hz3.00\u00d7108m\/s\u200b \u03bb=3.28\u2009m\\lambda = 3.28 \\, \\text{m}\u03bb=3.28m<\/p>\n\n\n\n<p>Thus, the wavelength of the radio waves is approximately <strong>3.28 meters<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>The wavelength is inversely related to the frequency: higher frequencies correspond to shorter wavelengths. In this case, the radio station&#8217;s frequency of 91.5 MHz corresponds to a wavelength of about 3.28 meters. Radio waves with higher frequencies, like those in the FM band, have shorter wavelengths compared to lower-frequency waves like those in the AM band.<\/p>\n\n\n\n<p>This wavelength is crucial in determining how radio waves propagate through the air and how antennas are designed for transmission and reception. The wavelength is typically measured in meters because it\u2019s more practical for the radio frequencies used in broadcasting.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner9-279.jpeg\" alt=\"\" class=\"wp-image-258971\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Beat (CKBT-FM) is a radio station broadcasting at 91.5 FM in Kitchener, Ontario. 91.5 The Beat Music Station.
