Electromagnetic radiation (light) consists of waves. More than acentury ago, scientists thought that light, like other waves,required a medium (called the ether) to support its transmission.Glass, having a typical mass density of ? = 2410 kg/m3, alsosupports the transmission of light. What would the elastic modulusof glass have to be to support the transmission of light waves at aspeed of v = 2.01 Â· 108 m/s? (For comparison: the actual elasticmodulus of window glass is 5 Â· 1010 N/m2.)

Electromagnetic radiation (light) consists of waves. More than a century ago, scientists thought that light, like other waves, required a medium (called the ether) to support its transmission. Glass, having a typical mass density of ? = 2670 kg/m3, also supports the transmission of light. What would the elastic modulus of glass have to be to support the transmission of light waves at a speed of v = 2.19 · 108 m/s? (For comparison: the actual elastic modulus of window glass is 5 · 1010 N/m2.)
