An alternating current. I Amperes, is given by i = 10sin2nft. where f is the frequenct in Hertz and t the time in seconds. What is the rate of change of current when t = 20ms given that f = 150 Hzπ​

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:

no
