Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Answer: (C) Dispersion of light
Blue colour of the sky is due to dispersion or scattering of light. The two most common types of matter present in the atmosphere are gaseous nitrogen and oxygen. These particles are most effective in scattering the higher frequency and shorter wavelength portions of the visible light spectrum.

Answer: (D) Design code
Computer code refers to the instructions that a computer can understand and execute. Source code is human-readable code written by programmers using a high-level programming language (e.g., Python, Java, C++).Object code is the output of a compiler after translating source code into machine-readable instructions, but it's not yet executable on its own and often needs to be linked with other object files. Machine code is the lowest-level programming language, directly executable by a computer's CPU. It consists of binary instructions (0s and 1s).Bytecode is an intermediate form of code that is typically executed by a virtual machine (like the Java Virtual Machine). It's platform-independent.

Answer: (C) Machine Language
Answer: (C) Machine Language
Machine language is the only computer language that is directly written and understood in binary codes (sequences of 0s and 1s). It is the lowest-level programming language and is specific to the computer's architecture. Every instruction that the CPU executes is in machine code. Assembly language uses mnemonics to represent machine code instructions, making it slightly more human-readable than raw binary, but it still requires an assembler to translate it into machine code. High-level languages are much more abstract and human-readable, requiring compilers or interpreters to translate them into machine code before execution.
