Activity sheet 2 Week 2 Calculations on Speed, Wavelength and Frequency
Directions: Solve the given problems using the equations below. Show your solution.
Use GUFSA (Given, Unknown, Formula, Solution, Answer)
The speed of electromagnetic waves in a vacuum is equal to the speed of light.
In equation form: c =

v = f x
Speed (v ): of the wave in meter/second (m/s)
Frequency (f) :number of waves that pass a cycle per second in Hertz (Hz)
Wavelength(m): is the distance from crest to crest or trough to trough.

Sample problem:
An X -ray photograph is taken with em waves that have a wavelength of 4 x 10-8 m and a speed of 3 x 108 m/s, Calculate the frequency.

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
