How is the wavelength of light related to its frequency?

Wavelength of light and frequency have inverse relationship.

Explanation:

Wavelength of light and frequency have inverse relationship. This is because Wave length is the distance between two successive crests or troughs while frequency is the number of waves passing through a specific point in one second.

It is cleared if the wavelength is larger less numbers of waves will pass through a given point and vice versa.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
