 * __ Worksheet __**

// 1)To put your calculator in scientific notation mode click “2nd” then “DRG” Select “Sci” and hit “enter.” To put it back, select “FLO” // // 2) Put all answers in scientific notation if large or small. Round all answers to two decimal places. (3.34583 x 10 // 14 // = 3.35 x 10 // 14 // ) // // 3) Show ALL work for each problem, and every number gets a unit. //


 * // Use the equation c=λf. //**


 * // Calculate the following questions. If given wavelength, solve for frequency and visa versa. //**


 * // Make sure all calculations for λ are done in m. //**


 * // Don’t get confused by the units of frequency. You will see them as Hz, 1/s or . c = 3 x 10 //** 8 ** //m/s.// **

**1) λ = 2.4 x 10** -8 **m**
 * //Remember to use the E button on your calculator for scientific notation.// **** // 3 x 10 // ** 8 ** // Is the same as 3E8. // **

**2) f=1.5 x 10** 15 **Hz (remember that Hz means the same as 1/s)**

3) λ= 5x10 -9 m

**4) f=3.23 x 10** 8 **1/s**

**5) λ= 6x10** -9 **m**

**6) f= 5.8 x 10** 14 **1/s**

**7) λ = 4x10** -8 **m**

**8) f=4.5 x 10** 18 **Hz**

**9) λ= 5x10** -8 **m**

**10) f=4.33 x 10** 19 **1/s**

**11) λ= 4.3x10** -13 **m**

**12) f= 4.2 x 10** 19 **Hz**

**13) λ = 5 x 10** -8 **m**

**14) f=1.8 x 10** 5 **Hz**

**15) λ= 3.6 x10** -7 **m**
