The wavelength of violet light with a frequency of 750 × 10^12 Hz is 400 nanometers (nm).
Wavelength is the distance between two consecutive peaks or troughs of a wave, representing the length of one complete cycle of the wave. It is commonly used to describe the size or scale of various types of waves, including electromagnetic waves such as light.
To calculate the wavelength of light, you can use the formula:
wavelength = speed of light/frequency
The speed of light is approximately 3.00 × 10^8 meters per second.
Let's plug in the values:
frequency = 750 × 10^12 Hz
speed of light = 3.00 × 10^8 m/s
wavelength = (3.00 × 10^8 m/s) / (750 × 10^12 Hz)
Simplifying the expression:
wavelength = (3.00 / 750) × (10^8 / 10^12) m
wavelength = 4.00 × 10^-4 m
Therefore, the wavelength of violet light is approximately 4.00 × 10^-4 meters or 400 nanometers (nm).

Human activities can increase the carrying capacity of the environment but can also cause environmental degradation and potential decrease in carrying capacity.
Human activities can have both advantages and disadvantages in terms of reducing their impact on the environment. One advantage is that development of food production methods and high-quality shelters can increase the carrying capacity of the environment, allowing more people to live. However, these technologies can also lead to environmental degradation, such as air pollution, water contamination, habitat loss, and climate change. The negative effects of increasing carrying capacity may even outweigh the positive ones, potentially decreasing the world's carrying capacity for human beings.

Thermal energy is the total internal kinetic energy due to the random motion of particles in an object, while heat is a form of energy transfer that happens due to a temperature difference between two objects or systems.
Heat and thermal energy are related concepts in physics but they are not the same thing. Thermal energy is the total internal kinetic energy of an object due to the random motion of its atoms and molecules. It is dependent on the temperature, mass, and type (or specific heat) of the material.
Heat, on the other hand, is a form of energy transfer that occurs due to a temperature difference between two objects or systems. It is the process of transfer of thermal energy from a hotter object to a cooler one. So, heat is a form of thermal energy in transit, typicallyg transferrin from areas of high temperature to areas of low temperature.
