Question

All of the following are true statements about electromagnetic radiation (light) except?
a. As energy increases frequency decreases
b. As wavelength increases energy decreases
c. As wavelength increases frequency decreases
d. The product of wavelength and frequency is constant

Answer 1

Answer:

I think it c............. .

Answer 2

Answer:

c

Explanation:

E = hv

where v = frequency

so E is directly proportional to frequency 1st statement is true.

E = hC/lemda

here

Energy is inversely proportional to wavelength so statement 2 is also correct .

v(frequency) = C/lemda

here frequency is inversely proportional to lemda so statement 3 is wrong .

v = C/lemda

lemda*v = C

Here v is frequency whose product with lemda is constant equals to Speed of light .

so statement 4 is also correct .
