How many fourths are equivalent to 2\8

1/4

Step-by-step explanation:

8/8=1

6/8=3/4

4/8=2/4

2/8=1/4

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
