Consider the diagram. planes m and n intersect at line d. lines a, b, and e are on plane m. line a is vertical and forms a right angle with line d. line b is diagonal and goes up and to the right. line e is at the top of the plane and is close to being horizontal. line c is on plane n and goes slightly up and to the right. lines a and d are non-coplanar. parallel. perpendicular. skew.

sine

step-by-step explanation:

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:

44
