The inverse variation equation shows the relationship between wavelength in meters, x, and frequency, y.

y = startfraction 3 x 10 superscript 8 baseline over x endfraction

what are the wavelengths for x-rays with frequency 3 × 1018?
1 × 10–10 m
3 × 10–10 m
3 × 1026 m
9 × 1026 m

The wavelength for X-rays with the given frequency is

Step-by-step explanation:

To calculate the wavelength of light, we use the equation:

where,

= wavelength of the light  

c = speed of light =

= frequency of light =

Putting the values in above equation, we get:

Hence, the wavelength for X-rays with the given frequency is

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
