- Comment on the relationship between the inter-element distance (7.5cm) and a wavelength of an EM wave (0.15m). What would be the effect on the inter-element distance if an EM wave at a higher frequency was used, assuming all other parameters were required to stay the same.(11%) Problem 7: Lasers can be constructed to produce an extremely high-intensity electromagnetic wave for a very brief time. Such lasers are called "pulsed lasers". They are used to ignite nuclear fusion, for example. Such a laser may produce an electromagnetic wave with a maximum electric field strength of 0.62 x 10 V/m for a time of 1.2 ns.
