Sam looks at the electromagnetic spectrum below.

After evaluating the electromagnetic spectrum, Sam accurately noted that as the wavelength

a
decreases, the frequency decreases.
b
decreases, the frequency increases.
c
increases, the frequency remains constant.
d
increases, the frequency increases.

b. decreases, the frequency increases.

In Store A, a video game that regularly sells for $59.99 is on sale at 10% off. In Store B, the same video game regularly sells for $64.99 and is on sale at 15% off. Which store sells the video game for the lower sale price?

For Store A, the sale price would be:

Sale price = regular price - (percent off * regular price)
Sale price = 59.99 - (0.10 * 59.99)
Sale price = 53.99

For Store B, the sale price would be:

Sale price = regular price - (percent off * regular price)
Sale price = 64.99 - (0.15 * 64.99)
Sale price = 55.24

Therefore, Store A sells the video game for the lower sale price.

To determine the relationship between wavelength and frequency in the electromagnetic spectrum, we can refer to the fundamental formula that relates the two quantities: the speed of light (c) equals the product of wavelength (λ) and frequency (ν).

c = λν

The speed of light is constant in a given medium, so if we assume that the speed of light remains constant, we can infer that any change in wavelength will be accompanied by a proportional change in frequency.

Therefore, the correct answer is (b) as the wavelength decreases, the frequency increases.
